  f2fs: fix UAF in f2fs_available_free_memory (2021-11-09 08:23:17 -0800)

----------------------------------------------------------------
f2fs-for-5.16-rc1

In this cycle, we've applied relatively small number of patches which fix subtle
corner cases mainly, while introducing a new mount option to be able to fragment
the disk intentionally for performance tests.

Enhancement:
 - add a mount option to fragmente on-disk layout to understand the performance
 - support direct IO for multi-partitions
 - add a fault injection of dquot_initialize

Bug fix:
 - address some lockdep complaints
 - fix a deadlock issue with quota
 - fix a memory tuning condition
 - fix compression condition to improve the ratio
 - fix disabling compression on the non-empty compressed file
 - invalidate cached pages before IPU/DIO writes

And, we've added some minor clean-ups as usual.
