Merge tag 'for-f2fs-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"New Features:
- uplift filesystem encryption into fs/crypto/
- give sysfs entries to control memroy consumption
Enhancements:
- aio performance by preallocating blocks in ->write_iter
- use writepages lock for only WB_SYNC_ALL
- avoid redundant inline_data conversion
- enhance forground GC
- use wait_for_stable_page as possible
- speed up SEEK_DATA and fiiemap
Bug Fixes:
- corner case in terms of -ENOSPC for inline_data
- hung task caused by long latency in shrinker
- corruption between atomic write and f2fs_trace_pid
- avoid garbage lengths in dentries
- revoke atomicly written pages if an error occurs
In addition, there are various minor bug fixes and clean-ups"
