Pull f2fs updates from Jaegeuk Kim: "In this round, we've got a huge number of patches that improve code readability along with minor bug fixes, while we've mainly fixed some critical issues in recently-added per-block age-based extent_cache, atomic write support, and some folio cases. Enhancements: - add sysfs nodes to set last_age_weight and manage discard_io_aware_gran - show ipu policy in debugfs - reduce stack memory cost by using bitfield in struct f2fs_io_info - introduce trace_f2fs_replace_atomic_write_block - enhance iostat support and adds flush commands Bug fixes: - revert "f2fs: truncate blocks in batch in __complete_revoke_list()" - fix kernel crash on the atomic write abort flow - call clear_page_private_reference in .{release,invalid}_folio - support .migrate_folio for compressed inode - fix cgroup writeback accounting with fs-layer encryption - retry to update the inode page given data corruption - fix kernel crash due to NULL io->bio - fix some bugs in per-block age-based extent_cache: - wrong calculation of block age - update age extent in f2fs_do_zero_range() - update age extent correctly during truncation" * tag 'f2fs-for-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (81 commits) f2fs: drop unnecessary arg for f2fs_ioc_*() f2fs: Revert "f2fs: truncate blocks in batch in __complete_revoke_list()" f2fs: synchronize atomic write aborts f2fs: fix wrong segment count f2fs: replace si->sbi w/ sbi in stat_show() f2fs: export ipu policy in debugfs f2fs: make kobj_type structures constant f2fs: fix to do sanity check on extent cache correctly f2fs: add missing description for ipu_policy node f2fs: fix to set ipu policy f2fs: fix typos in comments f2fs: fix kernel crash due to null io->bio f2fs: use iostat_lat_type directly as a parameter in the iostat_update_and_unbind_ctx() f2fs: add sysfs nodes to set last_age_weight f2fs: fix f2fs_show_options to show nogc_merge mount option f2fs: fix cgroup writeback accounting with fs-layer encryption f2fs: fix wrong calculation of block age f2fs: fix to update age extent in f2fs_do_zero_range() f2fs: fix to update age extent correctly during truncation f2fs: fix to avoid potential memory corruption in __update_iostat_latency() ...

f2fs: reduce stack memory cost by using bitfield in struct f2fs_io_info

2023-02-02T21:37:16Z

This patch tries to use bitfield in struct f2fs_io_info to improve memory usage. struct f2fs_io_info { ... unsigned int need_lock:8; /* indicate we need to lock cp_rwsem */ unsigned int version:8; /* version of the node */ unsigned int submitted:1; /* indicate IO submission */ unsigned int in_list:1; /* indicate fio is in io_list */ unsigned int is_por:1; /* indicate IO is from recovery or not */ unsigned int retry:1; /* need to reallocate block address */ unsigned int encrypted:1; /* indicate file is encrypted */ unsigned int post_read:1; /* require post read */ ... }; After this patch, size of struct f2fs_io_info reduces from 136 to 120.

f2fs: merge f2fs_show_injection_info() into time_to_inject()

2023-01-11T19:15:19Z

There is no need to additionally use f2fs_show_injection_info() to output information. Concatenate time_to_inject() and __time_to_inject() via a macro. In the new __time_to_inject() function, pass in the caller function name and parent function. In this way, we no longer need the f2fs_show_injection_info() function, and let's remove it.

f2fs: avoid to check PG_error flag

2023-01-06T23:13:41Z

After below changes: commit 14db0b3c7b83 ("fscrypt: stop using PG_error to track error status") commit 98dc08bae678 ("fsverity: stop using PG_error to track error status") There is no place in f2fs we will set PG_error flag in page, let's remove other PG_error usage in f2fs, as a step towards freeing the PG_error flag for other uses.

f2fs: add block_age-based extent cache

2022-12-12T22:53:56Z

This patch introduces a runtime hot/cold data separation method for f2fs, in order to improve the accuracy for data temperature classification, reduce the garbage collection overhead after long-term data updates. Enhanced hot/cold data separation can record data block update frequency as "age" of the extent per inode, and take use of the age info to indicate better temperature type for data block allocation: - It records total data blocks allocated since mount; - When file extent has been updated, it calculate the count of data blocks allocated since last update as the age of the extent; - Before the data block allocated, it searches for the age info and chooses the suitable segment for allocation. Test and result: - Prepare: create about 30000 files * 3% for cold files (with cold file extension like .apk, from 3M to 10M) * 50% for warm files (with random file extension like .FcDxq, from 1K to 4M) * 47% for hot files (with hot file extension like .db, from 1K to 256K) - create(5%)/random update(90%)/delete(5%) the files * total write amount is about 70G * fsync will be called for .db files, and buffered write will be used for other files The storage of test device is large enough(128G) so that it will not switch to SSR mode during the test. Benefit: dirty segment count increment reduce about 14% - before: Dirty +21110 - after: Dirty +18286 Signed-off-by: qixiaoyu1 Signed-off-by: xiongping1 Signed-off-by: Jaegeuk Kim
