[ Upstream commit 4b99ecd304290c4ef55666a62c89dfb2dbf0b2cd ]
Mapping info from dump.f2fs:
i_addr[0x2d] cluster flag [0xfffffffe : 4294967294]
i_addr[0x2e] [0x 10428 : 66600]

Previsouly, it missed to align fofs and ofs_in_node to cluster_size,
result in adding incorrect read extent cache, fix it.
Before:
f2fs_update_read_extent_tree_range: dev = (253,48), ino = 5, pgofs = 37, len = 4, blkaddr = 66600, c_len = 3
After:

Commit 3c6c2bebef79 ("f2fs: avoid punch_hole overhead when releasing
volatile data") introduced FI_FIRST_BLOCK_WRITTEN as below reason:
This patch is to avoid some punch_hole overhead when releasing volatile
data. If volatile data was not written yet, we just can make the first
page as zero.
After commit 7bc155fec5b3 ("f2fs: kill volatile write support"), we
won't support volatile write, but it missed to remove obsolete
FI_FIRST_BLOCK_WRITTEN, delete it in this patch.

commit e0d4e8acb3789c5a8651061fbab62ca24a45c063 upstream.
With gcc and W=1 option, there's a warning like this:
fs/f2fs/compress.c: In function ‘f2fs_init_page_array_cache’:
fs/f2fs/compress.c:1984:47: error: ‘%u’ directive writing between
1 and 7 bytes into a region of size between 5 and 8
[-Werror=format-overflow=]
1984 | sprintf(slab_name, "f2fs_page_array_entry-%u:%u", MAJOR(dev),
MINOR(dev));
| ^~
String "f2fs_page_array_entry-%u:%u" can up to 35. The first "%u" can up
to 4 and the second "%u" can up to 7, so total size is "24 + 4 + 7 = 35".
slab_name's size should be 35 rather than 32.

Pull f2fs updates from Jaegeuk Kim:
"In this cycle, we don't have a highlighted feature enhancement, but
mostly have fixed issues mainly in two parts: 1) zoned block device,
and 2) compression support.
For zoned block device, we've tried to improve the power-off recovery
flow as much as possible. For compression, we found some corner cases
caused by wrong compression policy and logics. Other than them, there
were some reverts and stat corrections.
Bug fixes:
- use finish zone command when closing a zone
- check zone type before sending async reset zone command
- fix to assign compress_level for lz4 correctly
- fix error path of f2fs_submit_page_read()
- don't {,de}compress non-full cluster
- send small discard commands during checkpoint back
- flush inode if atomic file is aborted
- correct to account gc/cp stats
And, there are minor bug fixes, avoiding false lockdep warning, and
clean-ups"

Pull f2fs updates from Jaegeuk Kim:
"In this round, we've added two features: F2FS_IOC_START_ATOMIC_REPLACE
and a per-block age-based extent cache.
F2FS_IOC_START_ATOMIC_REPLACE is a variant of the previous atomic
write feature which guarantees a per-file atomicity. It would be more
efficient than AtomicFile implementation in Android framework.
The per-block age-based extent cache implements another type of extent
cache in memory which keeps the per-block age in a file, so that block
allocator could split the hot and cold data blocks more accurately.
Enhancements:
- introduce F2FS_IOC_START_ATOMIC_REPLACE
- refactor extent_cache to add a new per-block-age-based extent cache support
- introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs
- add proc entry to show discard_plist info
- optimize iteration over sparse directories
- add barrier mount option
Bug fixes:
- avoid victim selection from previous victim section
- fix to enable compress for newly created file if extension matches
- set zstd compress level correctly
- initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot
- correct i_size change for atomic writes
- allow to read node block after shutdown
- allow to set compression for inlined file
- fix gc mode when gc_urgent_high_remaining is 1
- should put a page when checking the summary info
Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and
doc"

As a step towards freeing the PG_error flag for other uses, change ext4
and f2fs to stop using PG_error to track verity errors. Instead, if a
verity error occurs, just mark the whole bio as failed. The coarser
granularity isn't really a problem since it isn't any worse than what
the block layer provides, and errors from a multi-page readahead aren't
reported to applications unless a single-page read fails too.
f2fs supports compression, which makes the f2fs changes a bit more
complicated than desired, but the basic premise still works.
Note: there are still a few uses of PageError in f2fs, but they are on
the write path, so they are unrelated and this patch doesn't touch them.

Pull f2fs updates from Jaegeuk Kim:
"In this cycle, we mainly fixed some corner cases that manipulate a
per-file compression flag inappropriately. And, we found f2fs counted
valid blocks in a section incorrectly when zone capacity is set, and
thus, fixed it with additional sysfs entry to check it easily.
Lastly, this series includes several patches with respect to the new
atomic write support such as a couple of bug fixes and re-adding
atomic_write_abort support that we removed by mistake in the previous
release.
Enhancements:
- add sysfs entries to understand atomic write operations and zone
capacity
- introduce memory mode to get a hint for low-memory devices
- adjust the waiting time of foreground GC
- decompress clusters under softirq to avoid non-deterministic
latency
- do not skip updating inode when retrying to flush node page
- enforce single zone capacity
Bug fixes:
- set the compression/no-compression flags correctly
- revive F2FS_IOC_ABORT_VOLATILE_WRITE
- check inline_data during compressed inode conversion
- understand zone capacity when calculating valid block count
As usual, the series includes several minor clean-ups and sanity
checks"

Since pvec have 15 pages, it not a multiple of 4, when write compressed
pages, write in 64K as a unit, it will call pagevec_lookup_range_tag
agagin, sometimes this will take a lot of time.
Use onstack pages instead of pvec to mitigate this problem.

Now decompression is being handled in workqueue and it makes read I/O
latency non-deterministic, because of the non-deterministic scheduling
nature of workqueues. So, I made it handled in softirq context only if
possible, not in low memory devices, since this modification will
maintain decompresion related memory a little longer.

Pull filesystem folio updates from Matthew Wilcox:
"Primarily this series converts some of the address_space operations to
take a folio instead of a page.
Notably:
- a_ops->is_partially_uptodate() takes a folio instead of a page and
changes the type of the 'from' and 'count' arguments to make it
obvious they're bytes.
- a_ops->invalidatepage() becomes ->invalidate_folio() and has a
similar type change.
- a_ops->launder_page() becomes ->launder_folio()
- a_ops->set_page_dirty() becomes ->dirty_folio() and adds the
address_space as an argument.
There are a couple of other misc changes up front that weren't worth
separating into their own pull request"

As congestion is no longer tracked, congestion_wait() is effectively
equivalent to io_schedule_timeout().
So introduce f2fs_io_schedule_timeout() which sets TASK_UNINTERRUPTIBLE
and call that instead.

f2fs rw_semaphores work better if writers can starve readers,
especially for the checkpoint thread, because writers are strictly
more important than reader threads. This prevents significant priority
inversion between low-priority readers that blocked while trying to
acquire the read lock and a second acquisition of the write lock that
might be blocking high priority work.

This patch tries to mitigate lock contention between f2fs_write_checkpoint and
f2fs_get_node_info along with nat_tree_lock.
The idea is, if checkpoint is currently running, other threads that try to grab
nat_tree_lock would be better to wait for checkpoint.

There is a potential deadlock between writeback process and a process
performing write_begin() or write_cache_pages() while trying to write
same compress file, but not compressable, as below:
[Process A] - doing checkpoint
[Process B] [Process C]
f2fs_write_cache_pages()
- lock_page() [all pages in cluster, 0-31]
- f2fs_write_multi_pages()
- f2fs_write_raw_pages()
- f2fs_write_single_data_page()
- f2fs_do_write_data_page()
- return -EAGAIN [f2fs_trylock_op() failed]
- unlock_page(page) [e.g., page 0]
- generic_perform_write()
- f2fs_write_begin()
- f2fs_prepare_compress_overwrite()
- prepare_compress_overwrite()
- lock_page() [e.g., page 0]
- lock_page() [e.g., page 1]
- lock_page(page) [e.g., page 0]
Since there is no compress process, it is no longer necessary to hold
locks on every pages in cluster within f2fs_write_raw_pages().
This patch changes f2fs_write_raw_pages() to release all locks first
and then perform write same as the non-compress file in
f2fs_write_cache_pages().
