krbd: ignore zero-length requests
The old request code simply ignored zero-length requests
as soon as they were seen. The new request code currently
sends zero-length request out to the osd's. In order to
minimize behavioral changes in the new code, make zero-length
requests get ignored.
I've created http://tracker.ceph.com/issues/4236 to suggest
taking another look at this, specifically as it relates
to FLUSH operations.

commit 98a4b33438b09a70145fe53531c265418bc83a5f Author: Alex Elder <email@example.com> Date: Wed Feb 20 21:59:33 2013 -0600 rbd: ignore zero-length requests The old request code simply ignored zero-length requests. We should still operate that same way to avoid any changes in behavior. We can implement handling for special zero-length requests separately (see http://tracker.ceph.com/issues/4236). Add some assertions based on this new constraint. This resolves: http://tracker.ceph.com/issues/4237 Signed-off-by: Alex Elder <firstname.lastname@example.org>
