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) NFSv4: Add debugging printks to state manager NFSv4: Map NFS4ERR_SHARE_DENIED into an EACCES error instead of EIO NFSv4: update_changeattr does not need to set NFS_INO_REVAL_PAGECACHE NFSv4.1: nfs4_reset_session should use nfs4_handle_reclaim_lease_error NFSv4.1: Handle other occurrences of NFS4ERR_CONN_NOT_BOUND_TO_SESSION NFSv4.1: Handle NFS4ERR_CONN_NOT_BOUND_TO_SESSION in the state manager NFSv4.1: Handle errors in nfs4_bind_conn_to_session NFSv4.1: nfs4_bind_conn_to_session should drain the session NFSv4.1: Don't clobber the seqid if exchange_id returns a confirmed clientid NFSv4.1: Add DESTROY_CLIENTID NFSv4.1: Ensure we use the correct credentials for bind_conn_to_session NFSv4.1: Ensure we use the correct credentials for session create/destroy NFSv4.1: Move NFSPROC4_CLNT_BIND_CONN_TO_SESSION to the end of the operations NFSv4.1: Handle NFS4ERR_SEQ_MISORDERED when confirming the lease NFSv4: When purging the lease, we must clear NFS4CLNT_LEASE_CONFIRM NFSv4: Clean up the error handling for nfs4_reclaim_lease NFSv4.1: Exchange ID must use GFP_NOFS allocation mode nfs41: Use BIND_CONN_TO_SESSION for CB_PATH_DOWN* nfs4.1: add BIND_CONN_TO_SESSION operation NFSv4.1 test the mdsthreshold hint parameters ...
