Petersen" Cc: John Youn , Felipe Balbi , Greg KH , Thinh Nguyen , linux-usb@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-usb@vger.kernel.org Task ABORT TASK SET function is required by SCSI transport protocol standards (SAM-4 r14 section 7.3). It is similar to ABORT TASK function, but it applies to all commands received on a specified I_T nexus rather than a specific referenced command. Modify core_tmr_abort_task() to support TMR_ABORT_TASK_SET.
