  f2fs: fix to do sanity check on .cp_pack_total_block_count (2022-03-21 09:10:21 -0700)

----------------------------------------------------------------
f2fs-for-5.18

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.
