lglocks and brlocks are currently generated with some complicated macros in lglock.h. But there's no reason to not just use common utility functions and put all the data into a common data structure. In preparation, this patch changes the API to look more like normal function calls with pointers, not magic macros. The patch is rather large because I move over all users in one go to keep it bisectable. This impacts the VFS somewhat in terms of lines changed. But no actual behaviour change.

lglocks and brlocks are currently generated with some complicated macros in lglock.h. But there's no reason to not just use common utility functions and put all the data into a common data structure. Since there are at least two users it makes sense to share this code in a library. This is also easier maintainable than a macro forest. This will also make it later possible to dynamically allocate lglocks and also use them in modules (this would both still need some additional, but now straightforward, code) [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Andi Kleen <ak@linux.intel.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

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 ...
