NFS client patches for Linux 2.6.7

The following set of patches fix known issues with the 2.6.7 NFS client code, and significantly enhance the support for NFSv4.

linux-2.6.7-01-lock_owner_fixup.dif:

VFS,NFSv4: Fix locking code so that it uses current->tgid to determine whether or not locks are the same. Remove current->files lockowner

Signed-off-by: Trond Myklebust <trond.myklebust@fys.uio.no>

linux-2.6.7-02-lock_fix_cleanup.dif:

NFS: Ensure that we always clean up any resulting locks if we interrupt a process in the middle of a locking RPC call. Clean up locking code

Signed-off-by: Trond Myklebust <trond.myklebust@fys.uio.no>

linux-2.6.7-03-access.dif:

NFSv3/v4: be more efficient when doing ACCESS RPC calls. Always ask for the full set of permissions.

Signed-off-by: Trond Myklebust <trond.myklebust@fys.uio.no>

linux-2.6.7-04-open_revalidate.dif:

NFSv4: Optimizing away the case of negative dentries in nfs_open_revalidate() avoids several atomicity problems.

Signed-off-by: Trond Myklebust <trond.myklebust@fys.uio.no>

linux-2.6.7-05-fix_symlink.dif:

NFSv4: Fix the symlink overflow bug.

Signed-off-by: Trond Myklebust <trond.myklebust@fys.uio.no>

linux-2.6.7-06-nfs4_exception.dif:

NFSv4: Fix up the exception handling. Ensure we always handle NFS4ERR_DELAY properly.

Signed-off-by: Trond Myklebust <trond.myklebust@fys.uio.no>

linux-2.6.7-07-reboot_recovery.dif:

NFSv4: Clean up the reboot recovery. Ensure that we exclude stateful operations by using a per-server read/write semaphore.

Signed-off-by: Trond Myklebust <trond.myklebust@fys.uio.no>

linux-2.6.7-08-recover_locks.dif:

NFSv4: On server reboot we need to recover byte-range locks.

linux-2.6.7-10-file_ctx.dif:

NFSv2/v3/v4: Place NFS nfs_page shared data into a single structure that hangs off filp->private_data. As a side effect, this also cleans up the NFSv4 private file state info.

Signed-off-by: Trond Myklebust <trond.myklebust@fys.uio.no>
