lease and lock patches

lease and lock patches

[J. Bruce Fields]

Please pull from the 'for-linus' branch at

  git://linux-nfs.org/~bfields/linux.git for-linus

for a series of patches which add a setlease() file method.  The
longer-term goal is to allow cluster and network filesystems to give out
consistent leases when possible, in particular to allow nfsd to give out
delegations on cluster filesystems.  For now, though, we're using this
just to disallow leases selectively on certain filesystems (nfs and gfs2
for now) where they don't make sense.

Also includes some minor locks.c cleanup.

J. Bruce Fields (9):
      locks: convert an -EINVAL return to a BUG
      locks: clean up lease_alloc()
      locks: share more common lease code
      locks: rename lease functions to reflect locks.c conventions
      locks: provide a file lease method enabling cluster-coherent leases
      locks: export setlease to filesystems
      nfs: disable leases over NFS
      locks: make posix_test_lock() interface more consistent
      locks: fix vfs_test_lock() comment

Marc Eshel (1):
      gfs2: stop giving out non-cluster-coherent leases

      leases: minor break_lease() comment clarification

Would it still be possible to merge this for 2.6.23?  They've been
through linux-fsdevel, Christoph has taken a pass through them, and I
don't know of any unaddressed problems.
