[PATCH] SCSI: Introduce scsi_req_abort_cmd (REPOST)
Introduce scsi_req_abort_cmd(struct scsi_cmnd *). This function requests that SCSI Core start recovery for the command by deleting the timer and adding the command to the eh queue. It can be called by either LLDDs or SCSI Core. LLDDs who implement their own error recovery MAY ignore the timeout event if they generated scsi_req_abort_cmd.
