      Pull GFS2 updates from Bob Peterson:
       "We've got eight GFS2 patches for this merge window:
         - Andreas Gruenbacher has four patches related to cleaning up the
           GFS2 inode evict process. This is about half of his patches
           designed to fix a long-standing GFS2 hang related to the inode
           shrinker: Shrinker calls gfs2 evict, evict calls DLM, DLM requires
           memory and blocks on the shrinker.
           These four patches have been well tested. His second set of patches
           are still being tested, so I plan to hold them until the next merge
           window, after we have more weeks of testing. The first patch
           eliminates the flush_delayed_work, which can block.
         - Andreas's second patch protects setting of gl_object for rgrps with
           a spin_lock to prevent proven races.
         - His third patch introduces a centralized mechanism for queueing
           glock work with better reference counting, to prevent more races.
          -His fourth patch retains a reference to inode glocks when an error
           occurs while creating an inode. This keeps the subsequent evict
           from needing to reacquire the glock, which might call into DLM and
           block in low memory conditions.
         - Arvind Yadav has a patch to add const to attribute_group
         - I have a patch to detect directory entry inconsistencies and
           withdraw the file system if any are found. Better that than silent
         - I have a patch to remove a vestigial variable from glock
           structures, saving some slab space.
         - I have another patch to remove a vestigial variable from the GFS2
           in-core superblock structure"

      Pull btrfs updates from David Sterba:
       "The core updates improve error handling (mostly related to bios), with
        the usual incremental work on the GFP_NOFS (mis)use removal,
        refactoring or cleanups. Except the two top patches, all have been in
        for-next for an extensive amount of time.
        User visible changes:
         - statx support
         - quota override tunable
         - improved compression thresholds
         - obsoleted mount option alloc_start
        Core updates:
         - bio-related updates:
             - faster bio cloning
             - no allocation failures
             - preallocated flush bios
         - more kvzalloc use, memalloc_nofs protections, GFP_NOFS updates
         - prep work for btree_inode removal
         - dir-item validation
         - qgoup fixes and updates
         - cleanups:
             - removed unused struct members, unused code, refactoring
             - argument refactoring (fs_info/root, caller -> callee sink)
             - SEARCH_TREE ioctl docs"
