From: Armen Baloyan Date: Wed, 21 Nov 2012 07:39:53 +0000 (-0500) Subject: [SCSI] qla2xxx: Properly set result field of bsg_job reply structure for success... X-Git-Tag: firefly_0821_release~3680^2~1457^2~28 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=63ea923a97cb0d78efcbbd229950e101588f0ddb;p=firefly-linux-kernel-4.4.55.git [SCSI] qla2xxx: Properly set result field of bsg_job reply structure for success and failure. FC transport on receiving bsg_job submission failure, calls bsg_job->job_done() and sets the bsg_job->reply->result the returned value. In contrast, when the success code (0) is returned fc transport doesn't call bsg_job->job_done() and doesn't populate bsg_job->reply->result.
