       "Besides the usual cleanups, this one brings:
      
         * Support for 5 new chipsets: Intel's ICH LPC and SCH Centerton,

      etc.

      Pull NFS client updates from Trond Myklebust:
       "New features include:
         - Rewrite the O_DIRECT code so that it can share the same coalescing
           and pNFS functionality as the page cache code.
         - Allow the server to provide hints as to when we should use pNFS,
           and when it is more efficient to read and write through the
           metadata server.
         - NFS cache consistency updates:
           * Use the ctime to emulate a change attribute for NFSv2/v3 so that
             all NFS versions can share the same cache management code.
           * New cache management code will only look at the change attribute
             and size attribute when deciding whether or not our cached data
             is still valid or not.
           * Don't request NFSv4 post-op attributes on writes in cases such as
             O_DIRECT, where we don't care about data cache consistency, or
             when we have a write delegation, and know that our cache is still
             consistent.
           * Don't request NFSv4 post-op attributes on operations such as
             COMMIT, where there are no expected metadata updates.
           * Don't request NFSv4 directory post-op attributes in cases where
             the operations themselves already return change attribute
             updates: i.e. operations such as OPEN, CREATE, REMOVE, LINK and
             RENAME.
         - Speed up 'ls' and friends by using READDIR rather than READDIRPLUS
           if we detect no attempts to lookup filenames.
         - Improve the code sharing between NFSv2/v3 and v4 mounts
         - NFSv4.1 state management efficiency improvements
         - More patches in preparation for NFSv4/v4.1 migration functionality."
      
      Fix trivial conflict in fs/nfs/nfs4proc.c that was due to the dcache
      qstr name initialization changes (that made the length/hash a 64-bit
      union)

      tty: fix ldisc lock inversion trace · 8f6576ad
      Alan Cox authored
      This is caused by tty_release using tty_lock_pair to lock both sides of
      the pty/tty pair, and then tty_ldisc_release dropping and relocking one
      side only.  We can drop both fine, so drop both to avoid any lock
      ordering concerns.
      
      Rework the release path to fix the new locking model.

      pty: Fix lock inversion · d3ca8b64
      Alan Cox authored
      The ptmx_open path takes the tty and devpts locks in the wrong order
      because tty_init_dev locks and returns a locked tty.  As far as I can
      tell this is actually safe anyway because the tty being returned is new
      so nobody can get a reference to lock it at this point.
      
      However we don't even need the devpts lock at this point, it's only held
      as a byproduct of the way the locks were pushe down.
