NeilBrown <neil@brown.name> says:
This series of patches for overlayfs is primarily focussed on preparing
for some proposed changes to directory locking. In the new scheme we
will lock individual dentries in a directory rather than the whole
directory.
ovl currently will sometimes lock a directory on the upper filesystem
and do a few different things while holding the lock. This is
incompatible with the new scheme.
This series narrows the region of code protected by the directory lock,
taking it multiple times when necessary. This theoretically open up the
possibilty of other changes happening on the upper filesytem between the
unlock and the lock. To some extent the patches guard against that by
checking the dentries still have the expect parent after retaking the
lock. In general, I think ovl would have trouble if upperfs were being
changed independantly, and I don't think the changes here increase the
problem in any important way.
After this series (with any needed changes) lands I will resubmit my
change to vfs_rmdir() behaviour to have it drop the lock on error. ovl
will be much better positioned to handle that change. It will come with
the new "lookup_and_lock" API that I am proposing.

The only remaining user of ovl_cleanup() is ovl_cleanup_locked(), so we
no longer need both.
This patch renames ovl_cleanup() to ovl_cleanup_locked() and makes it
static.
ovl_cleanup_unlocked() is renamed to ovl_cleanup().

ovl_whiteout() relies on the workdir i_rwsem to provide exclusive access
to ofs->whiteout which it manipulates. Rather than depending on this,
add a new mutex, "whiteout_lock" to explicitly provide the required
locking. Use guard(mutex) for this so that we can return without
needing to explicitly unlock.
Then take the lock on workdir only when needed - to lookup the temp name
and to do the whiteout or link.

Rather than locking the directory(s) before calling
ovl_cleanup_and_whiteout(), change it (and ovl_whiteout()) to do the
locking, so the locking can be fine grained as will be needed for
proposed locking changes.
Sometimes this is called to whiteout something in the index dir, in
which case only that dir must be locked. In one case it is called on
something in an upperdir, so two directories must be locked. We use
ovl_lock_rename_workdir() for this and remove the restriction that
upperdir cannot be indexdir - because now sometimes it is.

This code:
performs a lookup_upper
creates a whiteout object
renames the whiteout over the result of the lookup
The create and the rename must be locked separately for proposed
directory locking changes. This patch takes a first step of moving the
lookup out of the locked region. A subsequent patch will separate the
create from the rename.

ovl currently locks a directory or two and then performs multiple actions
in one or both directories. This is incompatible with proposed changes
which will lock just the dentry of objects being acted on.
This patch moves calls to ovl_create_temp() out of the locked regions and
has it take and release the relevant lock itself.
The lock that was taken before this function was called is now taken
after. This means that any code between where the lock was taken and
ovl_create_temp() is now unlocked. This necessitates the use of
ovl_cleanup_unlocked() and the creation of ovl_lookup_upper_unlocked().
These will be used more widely in future patches.
Now that the file is created before the lock is taken for rename, we
need to ensure the parent wasn't changed before the lock was gained.
ovl_lock_rename_workdir() is changed to optionally receive the dentries
that will be involved in the rename. If either is present but has the
wrong parent, an error is returned.

ovl_copy_up_workdir() to before the lock is taken.

If ovl_copy_up_data() fails the error is not immediately handled but the
code continues on to call ovl_start_write() and lock_rename(),
presumably because both of these locks are needed for the cleanup.
Only then (if the lock was successful) is the error checked.
This makes the code a little hard to follow and could be fragile.
This patch changes to handle the error after the ovl_start_write()
(which cannot fail, so there aren't multiple errors to deail with). A
new ovl_cleanup_unlocked() is created which takes the required directory
lock. This will be used extensively in later patches.
In general we need to check the parent is still correct after taking the
lock (as ovl_copy_up_workdir() does after a successful lock_rename()) so
that is included in ovl_cleanup_unlocked() using new ovl_parent_lock()
and ovl_parent_unlock() calls (it is planned to move this API into VFS code
eventually, though in a slightly different form).

Case folding is often applied to subtrees and not on an entire
filesystem.
Disallowing layers from filesystems that support case folding is over
limiting.
Replace the rule that case-folding capable are not allowed as layers
with a rule that case folded directories are not allowed in a merged
directory stack.
Should case folding be enabled on an underlying directory while
overlayfs is mounted the outcome is generally undefined.
Specifically in ovl_lookup(), we check the base underlying directory
and fail with -ESTALE and write a warning to kmsg if an underlying
directory case folding is enabled.

Many simple GPIO controllers without interrupt capability have the same

have no other resources (like clocks).
Note that "ngpios" is now allowed in some cases it wasn't before and

struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.

As of commit 92ac7de3175e3 ("gpiolib: don't allow setting values on input
lines"), the GPIO core makes sure values cannot be set on input lines.
Remove the unnecessary check.

The hccs_get_all_spec_port_idle_sta() will tell user which port
is busy when firmware doesn't allow to decrease HCCS lane number.
However, the current log prints the index of die and port instead
of the hardware ID user perceived.

In scheduled scan mode, the current probe request only includes the SSID
IE, but omits the Basic Rate IE. Some APs do not respond to such
incomplete probe requests, causing net-detect failures. To improve
interoperability and ensure APs respond correctly, add the Basic Rate IE
to the probe request in driver.

Update the min, max ranges of the PLL clocks according to the latest
datasheet to be coherent in the driver. This patch solves the issues in
configuring the clocks related to peripherals with the desired frequency
within the range.
