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.

=================== ===========
mode=%s Control block allocation mode which supports "adaptive"
and "lfs". In "lfs" mode, there should be no random
writes towards main area.
"fragment:segment" and "fragment:block" are newly added here.
These are developer options for experiments to simulate filesystem
fragmentation/after-GC situation itself. The developers use these
modes to understand filesystem fragmentation/after-GC condition well,
and eventually get some insights to handle them better.
In "fragment:segment", f2fs allocates a new segment in ramdom
position. With this, we can simulate the after-GC condition.
In "fragment:block", we can scatter block allocation with
"max_fragment_chunk" and "max_fragment_hole" sysfs nodes.
We added some randomness to both chunk and hole size to make
it close to realistic IO pattern. So, in this mode, f2fs will allocate
1..<max_fragment_chunk> blocks in a chunk and make a hole in the
length of 1..<max_fragment_hole> by turns. With this, the newly
allocated blocks will be scattered throughout the whole partition.
Note that "fragment:block" implicitly enables "fragment:segment"
option for more randomness.
Please, use these options for your experiments and we strongly
recommend to re-format the filesystem after using these options.
io_bits=%u Set the bit size of write IO requests. It should be set
with "mode=lfs".
usrquota Enable plain user disk quota accounting.
