[PATCH] scsi: remove meaningless scsi_cmnd->serial_number_at_timeout field
scsi_cmnd->serial_number_at_timeout doesn't serve any purpose anymore. All serial_number == serial_number_at_timeout tests are always true in abort callbacks. Kill the field. Also, as ->pid always equals ->serial_number and ->serial_number doesn't have any special meaning anymore, update comments above ->serial_number accordingly. Once we remove all uses of this field from all lldd's, this field should go. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
