Merge tag 'for-f2fs-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"New features:
- in-memory extent_cache
- fs_shutdown to test power-off-recovery
- use inline_data to store symlink path
- show f2fs as a non-misc filesystem
Major fixes:
- avoid CPU stalls on sync_dirty_dir_inodes
- fix some power-off-recovery procedure
- fix handling of broken symlink correctly
- fix missing dot and dotdot made by sudden power cuts
- handle wrong data index during roll-forward recovery
- preallocate data blocks for direct_io
... and a bunch of minor bug fixes and cleanups"
