Merge tag 'nfs-for-3.5-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
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)
* tag 'nfs-for-3.5-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (146 commits)
