Sage,
Is it possible that we can't reuse the op_t because it could be still there in
the messenger queue before calling parent->log_operation() ?

Huh..It seems the op_t is already copied in generate_subop() -> ::encode(*op_t,
wr->get_data());...So, this shouldn't be an issue..

Hello,
I find only ceph.client.admin can mount cephfs.

Hi,
same environment, after a test script, the io latency(get from sudo ceph
--admin-daemon /run/ceph/guests/ceph-client.*.asok per dump)
increase from about 4ms to 7.3ms
qemu version: debian 2.1.2
kernel:3.10.45-openstack-amd64
system: debian 7.8
ceph: 0.94.5
VM CPU number: 4 (cpu MHz : 2599.
Pre-allocated the volume by "DD" across the entire RBD before you do any
performance test:).
In this case, you may want to re-create the RBD, pre-allocate and try again.
