Linus Torvalds d54d35c501 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
