Merge tag 'f2fs-for-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this round, we've followed up to support some generic features such
as cgroup, block reservation, linking fscrypt_ops, delivering
write_hints, and some ioctls. And, we could fix some corner cases in
terms of power-cut recovery and subtle deadlocks.
Enhancements:
- bitmap operations to handle NAT blocks
- readahead to improve readdir speed
- switch to use fscrypt_*
- apply write hints for direct IO
- add reserve_root=%u,resuid=%u,resgid=%u to reserve blocks for root/uid/gid
- modify b_avail and b_free to consider root reserved blocks
- support cgroup writeback
- support FIEMAP_FLAG_XATTR for fibmap
- add F2FS_IOC_PRECACHE_EXTENTS to pre-cache extents
- add F2FS_IOC_{GET/SET}_PIN_FILE to pin LBAs for data blocks
- support inode creation time
Bug fixs:
- sysfile-based quota operations
- memory footprint accounting
- allow to write data on partial preallocation case
- fix deadlock case on fallocate
- fix to handle fill_super errors
- fix missing inode updates of fsync'ed file
- recover renamed file which was fsycn'ed before
- drop inmemory pages in corner error case
- keep last_disk_size correctly
- recover missing i_inline flags during roll-forward
Various clean-up patches were added as well"
