Linus Torvalds d0195c7d7a f2fs-for-5.13-rc1
In this round, we added a new mount option, "checkpoint_merge", which introduces
 a kernel thread dealing with the f2fs checkpoints. Once we start to manage the
 IO priority along with blk-cgroup, the checkpoint operation can be processed in
 a lower priority under the process context. Since the checkpoint holds all the
 filesystem operations, we give a higher priority to the checkpoint thread all
 the time.
 
 Enhancement:
 - introduce gc_merge mount option to introduce a checkpoint thread
 - improve to run discard thread efficiently
 - allow modular compression algorithms
 - expose # of overprivision segments to sysfs
 - expose runtime compression stat to sysfs
 
 Bug fix:
 - fix OOB memory access by the node id lookup
 - avoid touching checkpointed data in the checkpoint-disabled mode
 - fix the resizing flow to avoid kernel panic and race conditions
 - fix block allocation issues on pinned files
 - address some swapfile issues
 - fix hugtask problem and kernel panic during atomic write operations
 - don't start checkpoint thread in RO
 
 And, we've cleaned up some kernel coding style and build warnings. In addition,
 we fixed some minor race conditions and error handling routines.
