    Merge tag 'for-f2fs-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs · 4fc29c1a
    Linus Torvalds authored
    Pull f2fs updates from Jaegeuk Kim:
     "The major change in this version is mitigating cpu overheads on write
      paths by replacing redundant inode page updates with mark_inode_dirty
      calls.  And we tried to reduce lock contentions as well to improve
      filesystem scalability.  Other feature is setting F2FS automatically
      when detecting host-managed SMR.
    
      Enhancements:
       - ioctl to move a range of data between files
       - inject orphan inode errors
       - avoid flush commands congestion
       - support lazytime
    
      Bug fixes:
       - return proper results for some dentry operations
       - fix deadlock in add_link failure
       - disable extent_cache for fcollapse/finsert"
