Pull f2fs updates from Jaegeuk Kim: "In this round, the changes primarily focus on resolving race conditions, memory safety issues (UAF), and improving the robustness of garbage collection (GC), and folio management. Enhancements: - add page-order information for large folio reads in iostat - add defrag_blocks sysfs node Bug fixes: - fix uninitialized kobject put in f2fs_init_sysfs() - disallow setting an extension to both cold and hot - fix node_cnt race between extent node destroy and writeback - preserve previous reserve_{blocks,node} value when remount - freeze GC and discard threads quickly - fix false alarm of lockdep on cp_global_sem lock - fix data loss caused by incorrect use of nat_entry flag - skip empty sections in f2fs_get_victim - fix inline data not being written to disk in writeback path - fix fsck inconsistency caused by FGGC of node block - fix fsck inconsistency caused by incorrect nat_entry flag usage - call f2fs_handle_critical_error() to set cp_error flag - fix fiemap boundary handling when read extent cache is incomplete - fix use-after-free of sbi in f2fs_compress_write_end_io() - fix UAF caused by decrementing sbi->nr_pages[] in f2fs_write_end_io() - fix incorrect file address mapping when inline inode is unwritten - fix incomplete search range in f2fs_get_victim when f2fs_need_rand_seg is enabled - avoid memory leak in f2fs_rename()" * tag 'f2fs-for-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (35 commits) f2fs: add page-order information for large folio reads in iostat f2fs: do not support mmap write for large folio f2fs: fix uninitialized kobject put in f2fs_init_sysfs() f2fs: protect extension_list reading with sb_lock in f2fs_sbi_show() f2fs: disallow setting an extension to both cold and hot f2fs: fix node_cnt race between extent node destroy and writeback f2fs: allow empty mount string for Opt_usr|grp|projjquota f2fs: fix to preserve previous reserve_{blocks,node} value when remount f2fs: invalidate block device page cache on umount f2fs: fix to freeze GC and discard threads quickly f2fs: fix to avoid uninit-value access in f2fs_sanity_check_node_footer f2fs: fix false alarm of lockdep on cp_global_sem lock f2fs: fix data loss caused by incorrect use of nat_entry flag f2fs: fix to skip empty sections in f2fs_get_victim f2fs: fix inline data not being written to disk in writeback path f2fs: fix fsck inconsistency caused by FGGC of node block f2fs: fix fsck inconsistency caused by incorrect nat_entry flag usage f2fs: fix to do sanity check on dcc->discard_cmd_cnt conditionally f2fs: refactor node footer flag setting related code f2fs: refactor f2fs_move_node_folio function ...
