Subject: ceph: wait on async create before checking caps for syncfs
From: Jeff Layton <jlayton@xxxxxxxxxx>
commit 8692969e9164c15474b356b9898e5b9b21a85643 upstream.
Currently, we'll call ceph_check_caps, but if we're still waiting
on the reply, we'll end up spinning around on the same inode in
flush_dirty_session_caps. Wait for the async create reply before
flushing caps.
