From e4a70e76add280db6068426716a9b2a74099144f Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 31 Mar 2006 20:36:47 +0900 Subject: [PATCH] [PATCH] libata: fix ata_qc_issue failure path On sg_err failure path, ata_qc_issue() doesn't mark the qc active before returning. This triggers WARN_ON() in __ata_qc_complete() when the qc gets completed. This patch moves ap->active_tag and QCFLAG_ACTIVE setting to the top of the function.
