We re-use the RESVSP/UNRESVSP ioctls from xfs which allow the user to allocate and deallocate regions to a file without zeroing data or changing i_size. Though renamed, the structure passed in from user is identical to struct xfs_flock64. The three fields that are actually used right now are l_whence, l_start and l_len. This should get ocfs2 immediate compatibility with userspace software using the pre-existing xfs ioctls. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
