[PATCH v2 0/2] NFSD: Add ALLOCATE and DEALLOCATE support

From: Anna Schumaker <Anna.Schumaker@Netapp.com>

These patches add server support for the ALLOCATE and DEALLOCATE operations
part of NFS v4.2.

I submitted my do_fallocate() -> vfs_fallocate() change as a separate patch,
so it has been removed from this submission. However, this code still depends
on this patch being applied first.

Changes in v2:
- ALLOCATE and DEALLOCATE can call a common nfsd4_fallocate() to check the
stateids, look up the file, and eventually call nfsd4_vfs_fallocate().
- I return NFS4ERR_INVAL in the case that vfs_fallocate() returns -ENODEV.
Please let me know if there is a better error to return instead!

These patches and the corresponding client changes are available in the
[fallocate] branch of:

git://git.linux-nfs.org/projects/anna/linux-nfs.git
