Ceph » rbd

when working on a large rbd image, I am hitting an
assertion failure in rbd kernel module; the
assertion is in rbd_img_obj_callback()

rbd_assert(img_request != NULL);

The test is a sequential write on an rbd
image, format 1. The size of the image is 1 TByte,
order is 22 (i.e. default object size).

The code of the rbd (and libceph) kernel modules is
from kernel.org, 3.10-rc6, running on a 3.0.80-0.5 kernel.

The problem looks like the rbd_obj_request structure in
question has been released already when processing of
the reponse to the original request takes place.
