    Merge tag 'f2fs-for-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs · a02cd422
    Linus Torvalds authored
    Pull f2fs updates from Jaegeuk Kim:
     "In this round, we introduce sysfile-based quota support which is
      required for Android by default. In addition, we allow that users are
      able to reserve some blocks in runtime to mitigate performance drops
      in low free space.
       - assign proper data segments according to write_hints given by user
       - issue cache_flush on dirty devices only among multiple devices
       - exploit cp_error flag and add more faults to enhance fault
         injection test
       - conduct more readaheads during f2fs_readdir
       - add a range for discard commands
      Bug fixes:
       - fix zero stat->st_blocks when inline_data is set
       - drop crypto key and free stale memory pointer while evict_inode is
       - fix some corner cases in free space and segment management
       - fix wrong last_disk_size
      This series includes lots of clean-ups and code enhancement in terms
      of xattr operations, discard/flush command control. In addition, it
      adds versatile debugfs entries to monitor f2fs status"
