  f2fs: add page-order information for large folio reads in iostat (2026-04-18 22:44:42 +0000)

----------------------------------------------------------------
f2fs-for-7.1-rc1

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.

Enhancement:
 - add page-order information for large folio reads in iostat
 - add defrag_blocks sysfs node

Bug fix:
 - 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
 - fix to preserve previous reserve_{blocks,node} value when remount
 - fix to 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
 - fix to 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
 - fix to avoid memory leak in f2fs_rename()
