X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bb0003c1e189d5766b6b39299b08c690c985c4dc;p=linux-2.6

[SCSI] make scsi_check_sense HARDWARE_ERROR return ADD_TO_MLQUEUE on retry

Change scsi_check_sense HARDWARE_ERROR check to return ADD_TO_MLQUEUE
if device->retry_hwerror is set to allow retries to occur without
restriction of blk_noretry_request check.
