linux-stable.git/fs/f2fs/data.c, branch v6.14

Merge tag 'f2fs-for-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

2025-01-28T04:58:58+00:00

Pull f2fs updates from Jaegeuk Kim:
 "In this series, there are several major improvements such as folio
  conversion by Matthew, speed-up of block truncation, and caching more
  dentry pages.

  In addition, we implemented a linear dentry search to address recent
  unicode regression, and figured out some false alarms that we could
  get rid of.

  Enhancements:
   - foilio conversion in various IO paths
   - optimize f2fs_truncate_data_blocks_range()
   - cache more dentry pages
   - remove unnecessary blk_finish_plug
   - procfs: show mtime in segment_bits

  Bug fixes:
   - introduce linear search for dentries
   - don't call block truncation for aliased file
   - fix using wrong 'submitted' value in f2fs_write_cache_pages
   - fix to do sanity check correctly on i_inline_xattr_size
   - avoid trying to get invalid block address
   - fix inconsistent dirty state of atomic file"

mm, swap: clean up device availability check

2025-01-26T04:22:36+00:00

Remove highest_bit and lowest_bit.  After the HDD allocation path has been
removed, the only purpose of these two fields is to determine whether the
device is full or not, which can instead be determined by checking the
inuse_pages.

f2fs: fix using wrong 'submitted' value in f2fs_write_cache_pages

2025-01-13T18:49:38+00:00

When f2fs_write_single_data_page fails, f2fs_write_cache_pages
will use the last 'submitted' value incorrectly, which will cause
'nwritten' and 'wbc->nr_to_write' calculation errors

f2fs: cache more dentry pages

2024-12-16T16:12:28+00:00

While traversing dir entries in dentry page, it's better to refresh current
accessed page in lru list by using FGP_ACCESSED flag, otherwise, such page
may has less chance to survive during memory reclaim, result in causing
additional IO when revisiting dentry page.

f2fs: Remove calls to folio_file_mapping()

2024-12-16T16:12:26+00:00

All folios that f2fs sees belong to f2fs and not to the swapcache
so it can dereference folio->mapping directly like all other
filesystems do.

in a folio.

f2fs: Use a data folio in f2fs_submit_page_bio()

2024-12-16T16:12:19+00:00

Remove a call to compound_head().  We can call bio_add_folio_nofail()
here because we just allocated the bio, so we know it can't fail and
thus the error path can never be taken.

f2fs: Use a folio more in f2fs_submit_page_bio()

2024-12-16T16:12:16+00:00

Cache the result of page_folio(fio->page) in a local variable so
we don't have to keep calling it.  Saves a couple of calls to
compound_head() and removes an access to page->mapping.
