Pull f2fs updates from Jaegeuk Kim: "In this round, key enhancements focus on reducing inode management memory overhead, introducing resizable tail sections with unified pinned allocation, and boosting I/O throughput via parallel multi-device flushes and asynchronous f2fs_write_end_io() execution. We also add dynamic device alias reservations to allow on-the-fly space donation from user partitions. Alongside these features, critical bug fixes resolve folio race conditions, lingering dirty flags, dentry and block counter leaks, and potential deadloops in f2fs_fsync_node_pages(). Additional stability patches address error-path handling across symlink, sync, and rename/unlink operations, prevent pinned file fragmentation, and correct segment migration and free section accounting in free_segment_range. Enhancements: - reduce memory footprint of ino management - support dynamic reserve/release for device aliasing - issue multi-device flushes in parallel - add a way to run f2fs_write_end_io() asynchronously - support resizable tail section and unify pinned allocation Bug fixes: - fix to pass folio->index to f2fs_sanity_check_node_footer() - fix folio_nr_pages() race after put in large folio invalidate - fix to clear dirty flag on folio in error path - accurately adjust free_sections during free_segment_range - fix to avoid potential deadloop in f2fs_fsync_node_pages() - fix the error path in symlink, device alias in rename/unlink, f2fs_sync_fs - fix to migrate all curseg types during free_segment_range - fix to avoid pinfile fragment on fragment:{block, segment} mode - fix valid block count leak on data block allocation failure - fix dentry folio leak in find_in_level - reject overlapping move range after len expansion - fix some bugs related to file pinning, GC functions, i_size And, the series includes a number of minor bug fixes" * tag 'f2fs-for-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (51 commits) f2fs: support resizable tail section and unify pinned allocation f2fs: don't leave the hashed inode while it's unlinked f2fs: accurately adjust free_sections during free_segment_range f2fs: fix to avoid potential deadloop in f2fs_fsync_node_pages() f2fs: use adjusted write range after f2fs_write_checks() f2fs: fix to propagate error from f2fs_sync_fs() f2fs: return symlink writeback errors f2fs: fix error handling on device alias check in rename and unlink f2fs: fix to reset all pinned status during fggc f2fs: use f2fs_{down, up}_(read, write}_trace() for nat_tree_lock f2fs: reduce memory footprint of ino management f2fs: fix i_size when pinned fallocate partially fails f2fs: fix to migrate all curseg types during free_segment_range f2fs: avoid setting SBI_NEED_FSCK on transient resize failure f2fs: fix to avoid pinfile fragment on fragment:{block, segment} mode f2fs: cleanup w/ f2fs_need_rand_{blk, seg, seg_blk} f2fs: fix to shrink gc_lock coverage in f2fs_gc_range() f2fs: fix to reclaim space in f2fs_allocate_pinning_section() f2fs: unify add/remove ino entry API for all ino types f2fs: fix to zero post-EOF data when extending file size ...
