From 7498e99fc51ca60b960ef79061e0e7b521feb07e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Matias=20Bj=C3=B8rling?= Date: Mon, 28 Nov 2016 22:38:52 +0100 Subject: [PATCH] nvme: lightnvm: frees wrong cmd structure MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When struct nvme_request was introduced, the nvme_nvm_submit_io was converted to the new interface. The interface moves nvme_nvm_command data structure into the struct request pdu. On io completion, rq->cmd is freed, which should have been the dereferenced pdu nvme_request->cmd.
