The delegation code mostly pretends to support either read or write delegations. However, correct support for write delegations would require, for example, breaking of delegations (and/or implementation of cb_getattr) on stat. Currently all that stops us from handing out delegations is a subtle reference-counting issue. Avoid confusion by adding an earlier check that explicitly refuses write delegations. For now, though, I'm not going so far as to rip out existing half-support for write delegations, in case we get around to using that soon. Signed-off-by: NJ. Bruce Fields <bfields@redhat.com>
