Description

BUG at osd_client.c:978:

static void __remove_osd(struct ceph_osd_client *osdc, struct ceph_osd *osd)
{
    dout("__remove_osd %p\n", osd);
    BUG_ON(!list_empty(&osd->o_requests));
...

This happened when running a test script that tried to map a nonexistent image many times.
This was in VNC, so I don't have an exact trace, but it's in the error path of rbd_add():

__remove_osd()
ceph_osdc_stop()
ceph_destroy_client()
rbd_client_release()
rbd_dev_destroy()
rbd_add()
