Merge tag 'f2fs-for-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "In this cycle, f2fs has some performance improvements for Android workloads such as using read-unfair rwsems and adding some sysfs entries to control GCs and discard commands in more details. In addtiion, it has some tunings to improve the recovery speed after sudden power-cut. Enhancement: - add reader-unfair rwsems with F2FS_UNFAIR_RWSEM: will replace with generic API support - adjust to make the readahead/recovery flow more efficiently - sysfs entries to control issue speeds of GCs and Discard commands - enable idmapped mounts Bug fix: - correct wrong error handling routines - fix missing conditions in quota - fix a potential deadlock between writeback and block plug routines - fix a deadlock btween freezefs and evict_inode We've added some boundary checks to avoid kernel panics on corrupted images, and several minor code clean-ups" * tag 'f2fs-for-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (27 commits) f2fs: fix to do sanity check on .cp_pack_total_block_count f2fs: make gc_urgent and gc_segment_mode sysfs node readable f2fs: use aggressive GC policy during f2fs_disable_checkpoint() f2fs: fix compressed file start atomic write may cause data corruption f2fs: initialize sbi->gc_mode explicitly f2fs: introduce gc_urgent_mid mode f2fs: compress: fix to print raw data size in error path of lz4 decompression f2fs: remove redundant parameter judgment f2fs: use spin_lock to avoid hang f2fs: don't get FREEZE lock in f2fs_evict_inode in frozen fs f2fs: remove unnecessary read for F2FS_FITS_IN_INODE f2fs: introduce F2FS_UNFAIR_RWSEM to support unfair rwsem f2fs: avoid an infinite loop in f2fs_sync_dirty_inodes f2fs: fix to do sanity check on curseg->alloc_type f2fs: fix to avoid potential deadlock f2fs: quota: fix loop condition at f2fs_quota_sync() f2fs: Restore rwsem lockdep support f2fs: fix missing free nid in f2fs_handle_failed_inode f2fs: support idmapped mounts f2fs: add a way to limit roll forward recovery time ...
