Linus Torvalds 53f2c4a8fd NFS client updates for Linux 3.5
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)
