| Subject: iscsi-target: Add missing CMDSN_LOWER_THAN_EXP check in iscsit_handle_scsi_cmd |
| |
| From: Nicholas Bellinger <nab@linux-iscsi.org> |
| |
| commit 7e32da55e26b80d57961681e53aa67938268db3f upstream. |
| |
| This patch adds a missing CMDSN_LOWER_THAN_EXP return check for |
| iscsit_sequence_cmd() in iscsit_handle_scsi_cmd() that was incorrectly |
| dropped during the v3.1-rc cleanups to use iscsit_sequence_cmd(). |
