Hello Alex Elder,
This is a semi-automatic email about new static checker warnings.
The patch 64548e0638af: "rbd: enforce parent overlap" from Apr 21,
2013, leads to the following Smatch complaint:
drivers/block/rbd.c:1449 rbd_osd_read_callback()
error: we previously assumed 'img_request' could be null (see line 1448)
drivers/block/rbd.c
1447 img_request = obj_request->img_request;
1448 layered = img_request && img_request_layered_test(img_request);
^^^^^^^^^^^
Old check.
1449 rbd_dev = img_request->rbd_dev;
^^^^^^^^^^^^^^^^^^^^
New dereference.
1450 }
1451
regards,
dan carpenter
