Linus Torvalds d46dd0d883 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()
