nfsd: Add ALLOCATE support
The ALLOCATE operation is used to preallocate space in a file. I can do this by using vfs_fallocate() to do the actual preallocation. ALLOCATE only returns a status indicator, so we don't need to write a special encode() function. Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com> Signed-off-by: J.
