    Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
    
    Pull vfs updates from Al Viro:
     "In this one:
    
       - d_move fixes (Eric Biederman)
    
       - UFS fixes (me; locking is mostly sane now, a bunch of bugs in error
         handling ought to be fixed)
    
       - switch of sb_writers to percpu rwsem (Oleg Nesterov)
    
       - superblock scalability (Josef Bacik and Dave Chinner)
    
       - swapon(2) race fix (Hugh Dickins)"

      dcache: Handle escaped paths in prepend_path
      mm: fix potential data race in SyS_swapon
      inode: don't softlockup when evicting inodes
      inode: rename i_wb_list to i_io_list
      sync: serialise per-superblock sync operations
      inode: convert inode_sb_list_lock to per-sb
      inode: add hlist_fake to avoid the inode hash lock in evict
      writeback: plug writeback at a high level
      change sb_writers to use percpu_rw_semaphore
      shift percpu_counter_destroy() into destroy_super_work()
      percpu-rwsem: kill CONFIG_PERCPU_RWSEM
      percpu-rwsem: introduce percpu_rwsem_release() and percpu_rwsem_acquire()
      percpu-rwsem: introduce percpu_down_read_trylock()
      document rwsem_release() in sb_wait_write()
      fix the broken lockdep logic in __sb_start_write()
      introduce __sb_writers_{acquired,release}() helpers
      ufs_inode_get{frag,block}(): get rid of 'phys' argument
      ufs_getfrag_block(): tidy up a bit
