That means it's a request sent to a parent image. I see one thing that I'm suspicious of, but I'll need to look at it a bit to see if it's really a problem. In rbd_parent_request_destroy(), should this last line: rbd_img_request_destroy(kref); be this instead? rbd_img_request_put(parent_request); And get rid of this line above that: img_request_child_clear(parent_request); Something to look at. Also the fact that it's a parent request with two objects involved seems strange, but again, I'm just speculating at this point. -Alex > Mar 25 21:17:58 murmillia kernel: [ 2205.255957] ->obj_request_count 1 > Mar 25 21:17:58 murmillia kernel: [ 2205.255958] ->next_completion 2 > Mar 25 21:17:58 murmillia kernel: [ 2205.255959] ->xferred 45056 > Mar 25 21:17:58 murmillia kernel: [ 2205.255960] ->result 0 -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
