This one fixes a race which qemu had also in iscsi block driver
between cancellation and io completition.
qemu_rbd_aio_cancel was not synchronously waiting for the end of
the command.
To archieve this it introduces a new status flag which uses
-EINPROGRESS.
Changes since PATCHv5:

[PATCH 1/2] rbd: don't leak rbd_req on synchronous requests
[PATCH 2/2] rbd: don't leak rbd_req for rbd_req_sync_notify_ack()

To unsubscribe from this
When rbd_do_request() is called it allocates and populates an
rbd_req structure to hold information about the osd request to be
sent. This is done for the benefit of the callback function (in
particular, rbd_req_cb()), which uses this in processing when
the request completes.
Synchronous
When rbd_req_sync_notify_ack() calls rbd_do_request() it supplies
rbd_simple_req_cb() as its callback function. Because the callback
is supplied, an rbd_req structure gets allocated and populated so it
can be used by the callback. However rbd_simple_req_cb() is not
freeing (or even using) the

My initial tests using a 3.5.7 kernel with the 55 patches from
wip-nick are going well. So far I've gone through 8 installs without
an incident, I'll leave it run for a bit longer to see if it crops up

Can I get a branch with these patches integrated into all of the

The major points are:

2. Add the performance counter in Objecter to
