Subject: ceph: wait on async create before checking caps
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=ec5ed88dcee856ab4497e943ab068f91a057b3d2;p=ceph-client.git

ceph: wait on async create before checking caps

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. Wait for the
async create reply before we try to flush caps.
