Subject: [GIT PULL] f2fs update for 4.18-rc1
Hi Linus,
So sorry for a bit late pull request. I had to take a look at the test results
run during the weekend. Could you please consider this?
Thanks,

f2fs: fix to clear FI_VOLATILE_FILE correctly (2018-06-04 14:33:27 -0700)
----------------------------------------------------------------
f2fs-for-4.18-rc1
In this round, we've mainly focused on discard, aka unmap, control along with
fstrim for Android-specific usage model. In addition, we've fixed writepage flow
which returned EAGAIN previously resulting in EIO of fsync(2) due to mapping's
error state. In order to avoid old MM bug [1], we decided not to use __GFP_ZERO
for the mapping for node and meta page caches. As always, we've cleaned up many
places for future fsverity and symbol conflicts.
Enhancement:
- do discard/fstrim in lower priority considering fs utilization
- split large discard commands into smaller ones for better responsiveness
- add more sanity checks to address syzbot reports
- add a mount option, fsync_mode=nobarrier, which can reduce # of cache flushes
- clean up symbol namespace with modified function names
- be strict on block allocation and IO control in corner cases
Bug fix:
- don't use __GFP_ZERO for mappings
- fix error reports in writepage to avoid fsync() failure
- avoid selinux denial on CAP_RESOURCE on resgid/resuid
- fix some subtle race conditions in GC/atomic writes/shutdown
- fix overflow bugs in sanity_check_raw_super
- fix missing bits on get_flags
Clean-up:
- prepare the generic flow for future fsverity integration
- fix some broken coding standard
