So far we have the unfortunate situation that mdio_bus_phy_may_suspend()
is called in suspend AND resume path, assuming that function result is
the same. After the original change this is no longer the case,
resulting in broken resume as reported by Geert.
To fix this call mdio_bus_phy_may_suspend() in the suspend path only,
and let the phy_device store the info whether it was suspended by
MDIO bus PM.
Fixes: 503ba7c69610 ("net: phy: Avoid multiple suspends")

several iterations of ->atomic_open() calling conventions ago, we
used to need fput() if ->atomic_open() failed at some point after
successful finish_open(). Now (since 2016) it's not needed -
struct file carries enough state to make fput() work regardless
of the point in struct file lifecycle and discarding it on
failure exits in open() got unified. Unfortunately, I'd missed
the fact that we had an instance of ->atomic_open() (cifs one)
that used to need that fput(), as well as the stale comment in
finish_open() demanding such late failure handling. Trivially
fixed...

with the way fs/namei.c:do_last() had been done, ->atomic_open()
instances needed to recognize the case when existing file got
found with O_EXCL|O_CREAT, either by falling back to finish_no_open()
or failing themselves. gfs2 one didn't.

Currently, PF missed to clear the port base VLAN for VF when
unload. In this case, the VLAN id will remain in the VLAN
table. This patch fixes it.

According to the user manual, the ingress and egress VLAN filter
are configured at the same time. Currently, hclge_init_vlan_config()
and hclge_set_vlan_spoofchk() will both change the VLAN filter
switch. So it's necessary to read the old configuration before
modifying it.

Currently, if VF is loaded on the host side, the host doesn't
clear the VF's VLAN table entries when VF removing. In this
case, when doing reset and disabling sriov at the same time the
VLAN device over VF will be removed, but the VLAN table entries
in hardware are remained.
This patch fixes it by asking PF to clear the VLAN table entries for
VF when VF is removing. It also clears the VLAN table full bit
after VF VLAN table entries being cleared.

The HNS3 driver supports to configure TC numbers and TC to priority
map via "tc" tool. But when delete the rule, will fail, because
the HNS3 driver needs at least one TC, but the "tc" tool sets TC
number to zero when delete.
This patch makes sure that the TC number is at least one.

There was a bug that was causing packets to be sent to the driver
without first calling dequeue() on the "child" qdisc. And the KASAN
report below shows that sending a packet without calling dequeue()
leads to bad results.
The problem is that when checking the last qdisc "child" we do not set
the returned skb to NULL, which can cause it to be sent to the driver,
and so after the skb is sent, it may be freed, and in some situations a
reference to it may still be in the child qdisc, because it was never
dequeued.
The crash log looks like this:

Commit b72053072c0b ("block: allow partitions on host aware zone
devices") introduced the helper function disk_has_partitions() to check
if a given disk has valid partitions. However, since this function result
directly depends on the disk partition table length rather than the
actual existence of valid partitions in the table, it returns true even
after all partitions are removed from the disk. For host aware zoned
block devices, this results in zone management support to be kept
disabled even after removing all partitions.
Fix this by changing disk_has_partitions() to walk through the partition
table entries and return true if and only if a valid non-zero size
partition is found.

commit 01e99aeca397 ("blk-mq: insert passthrough request into
hctx->dispatch directly") may change to add flush request to the tail
of dispatch by applying the 'add_head' parameter of
blk_mq_sched_insert_request.
Turns out this way causes performance regression on NCQ controller because
flush is non-NCQ command, which can't be queued when there is any in-flight
NCQ command. When adding flush rq to the front of hctx->dispatch, it is
easier to introduce extra time to flush rq's latency compared with adding
to the tail of dispatch queue because of S_SCHED_RESTART, then chance of
flush merge is increased, and less flush requests may be issued to
controller.
So always insert flush request to the front of dispatch queue just like
before applying commit 01e99aeca397 ("blk-mq: insert passthrough request
into hctx->dispatch directly").

Devices are formatted in multiple of tracks.
For an Extent Space Efficient (ESE) volume we get errors when accessing
unformatted tracks. In this case the driver either formats the track on
the flight for write requests or returns zero data for read requests.
In case a request spans multiple tracks, the indication of an unformatted
track presented for the first track is incorrectly applied to all tracks
covered by the request. As a result, tracks containing data will be handled
as empty, resulting in zero data being returned on read, or overwriting
existing data with zero on write.
Fix by determining the track that gets the NRF error.
For write requests only format the track that is surely not formatted.
For Read requests all tracks before have returned valid data and should not
be touched.
All tracks after the unformatted track might be formatted or not. Those are
returned to the blocklayer to build a new request.
When using alias devices there is a chance that multiple write requests
trigger a format of the same track which might lead to data loss. Ensure
that a track is formatted only once by maintaining a list of currently
processed tracks.

The busy timeout for the CMD5 to put the eMMC into sleep state, is specific
to the card. Potentially the timeout may exceed the host->max_busy_timeout.
If that becomes the case, mmc_sleep() converts from using an R1B response
to an R1 response, as to prevent the host from doing HW busy detection.
However, it has turned out that some hosts requires an R1B response no
matter what, so let's respect that via checking MMC_CAP_NEED_RSP_BUSY. Note
that, if the R1B gets enforced, the host becomes fully responsible of
managing the needed busy timeout, in one way or the other.

The at24 driver attempts to read a byte from the device to validate that
it's actually present, and if not, disables the vcc regulator and
returns -ENODEV. However, between the read and the error handling path,
pm_runtime_idle() is called and invokes the driver's suspend callback,
which also disables the vcc regulator. This leads to an underflow of the
regulator enable count if the EEPROM is not present.
Move the pm_runtime_suspend() call to be after the error handling path
to resolve this.

Per the dt-binding the interrupt is optional so use
platform_get_irq_optional() instead of platform_get_irq(). Since
commit 7723f4c5ecdb ("driver core: platform: Add an error message to
platform_get_irq*()") platform_get_irq() produces an error message
orion-mdio f1072004.mdio: IRQ index 0 not found
which is perfectly normal if one hasn't specified the optional property
in the device tree.

We can simply move the memcg code after we release the listener lock,

s390/qeth: fixes 2020-03-11
please apply the following patch series for qeth to netdev's net tree.
Just one fix to get the RX buffer pool resizing right, with two
preparatory cleanups.
This is on the larger side given where we are in the -rc cycle, but a
big chunk of the delta is just refactoring to make the fix look nice.
I intentionally split these off from yesterday's series. No objections
if you'd rather punt them to net-next, the series should apply cleanly.

The RX buffer pool is allocated in qeth_alloc_qdio_queues().
A subsequent pool resizing is then handled in a very simple way:
first free the current pool, then allocate a new pool of the requested
size.
There's two ways where this can go wrong:
1. if the resize action happens _before_ the initial pool was allocated,
then a subsequent initialization will call qeth_alloc_qdio_queues()
and fill the pool with a second(!) set of pages. We consume twice the
planned amount of memory.
This is easy to fix - just skip the resizing if the queues haven't
been allocated yet.
2. if the initial pool was created by qeth_alloc_qdio_queues() but a
subsequent resizing fails, then the device has no(!) RX buffer pool.
The next initialization will _not_ call qeth_alloc_qdio_queues(), and
attempting to back the RX buffers with pages in
qeth_init_qdio_queues() will fail.
Not very difficult to fix either - instead of re-allocating the whole
pool, just allocate/free as many entries to match the desired size.

The Internet Assigned Numbers Authority (IANA) has recently assigned
a protocol number value of 143 for Ethernet [1].
Before this assignment, encapsulation mechanisms such as Segment Routing
used the IPv6-NoNxt protocol number (59) to indicate that the encapsulated
payload is an Ethernet frame.
In this patch, we add the definition of the Ethernet protocol number to the
kernel headers and update the SRv6 L2 tunnels to use it.

By default, DSA drivers should configure CPU and DSA ports to their
maximum speed. In many configurations this is sufficient to make the
link work.
In some cases it is necessary to configure the link to run slower,
e.g. because of limitations of the SoC it is connected to. Or back to
back PHYs are used and the PHY needs to be driven in order to
establish link. In this case, phylink is used.
Only instantiate phylink if it is required. If there is no PHY, or no
fixed link properties, phylink can upset a link which works in the
default configuration.

byte) and the passed size argument is 6. As a result, the logic will
also accept other, malformed strings, e.g. "eee_tiXXX:".

The default defintions use fill pattern 0x90 for padding which for ARC
generates unintended "ldh_s r12,[r0,0x20]" corresponding to opcode 0x9090
So use ".align 4" which insert a "nop_s" instruction instead.

Pull thread fix from Christian Brauner:
"This contains a single fix for a regression which was introduced when
we introduced the ability to select a specific pid at process creation
time.
When this feature is requested, the error value will be set to -EPERM
after exiting the pid allocation loop. This caused EPERM to be
returned when e.g. the init process/child subreaper of the pid
namespace has already died where we used to return ENOMEM before.
The first patch here simply fixes the regression by unconditionally
setting the return value back to ENOMEM again once we've successfully
allocated the requested pid number. This should be easy to backport to
v5.5.
The second patch adds a comment explaining that we must keep returning
ENOMEM since we've been doing it for a long time and have explicitly
documented this behavior for userspace. This seemed worthwhile because
we now have at least two separate example where people tried to change
the return value to something other than ENOMEM (The first version of
the regression fix did that too and the commit message links to an
earlier patch that tried to do the same.).
I have a simple regression test to make sure we catch this regression
in the future but since that introduces a whole new selftest subdir
and test files I'll keep this for v5.7"

Pull pin control fixes from Linus Walleij:
"Some pin control fixes for the v5.6 series.
It comes down to memory leaks in the core and driver fixes. Some
should have been sent earlier but they kept piling up and the world is
just so full of distractions these days.
- Fix some inverted pins in the Meson GLX driver.
- Align the i.MX SC message structs causing warnings from KASan.
- Balance the kref in pinctrl hogs so they are actually free:d when
removing a pin control module. We haven't seen it before as people
don't use modules for pin control that much, I think.
- Add a missing call to pinctrl_unregister_mappings() another memory
leak when using modules.
- Fix the fwspec parsing in the Qualcomm driver.
- Fix a syntax error in the Falcon driver.
- Assign .irq_eoi conditionally in the Qualcomm driver, fixing a bug
affecting elder Qualcomm platforms"
