  f2fs: use onstack pages instead of pvec (2022-08-05 04:20:55 -0700)

----------------------------------------------------------------
f2fs-for-6.0

In this cycle, we mainly fixed some corner cases that manipulate a per-file
compression flag inappropriately. And, we found f2fs counted valid blocks in a
section incorrectly when zone capacity is set, and thus, fixed it with
additional sysfs entry to check it easily. Lastly, this series includes
several patches with respect to the new atomic write support such as a
couple of bug fixes and re-adding atomic_write_abort support that we removed
by mistake in the previous release.

Enhancement:
 - add sysfs entries to understand atomic write operations and zone
   capacity
 - introduce memory mode to get a hint for low-memory devices
 - adjust the waiting time of foreground GC
 - decompress clusters under softirq to avoid non-deterministic latency
 - do not skip updating inode when retrying to flush node page
 - enforce single zone capacity

Bug fix:
 - set the compression/no-compression flags correctly
 - revive F2FS_IOC_ABORT_VOLATILE_WRITE
 - check inline_data during compressed inode conversion
 - understand zone capacity when calculating valid block count

As usual, the series includes several minor clean-ups and sanity checks.
