Message-ID: <20130903111436.GA15230@elgon.mountain> (raw)
Hello Vu Pham,
This is a semi-automatic email about new static checker warnings.
The patch 12050ce23475: "iser-target: introduce fast memory
registration mode (FRWR)" from Aug 28, 2013, leads to the following
Smatch complaint:
drivers/infiniband/ulp/isert/ib_isert.c:622 isert_connect_release()
warn: variable dereferenced before check 'device' (see line 598)
drivers/infiniband/ulp/isert/ib_isert.c
597 if (device->use_frwr)
^^^^^^^^^^^^^^^^
Patch introduces dereference.
598 isert_conn_free_frwr_pool(isert_conn);
599
[ snip ]
620 kfree(isert_conn);
621
622 if (device)
^^^^^^
Existing check.
623 isert_device_try_release(device);
624
regards,
dan carpenter
