From bc91ade9b7bc274d625c9b24c04d365a2daf481e Mon Sep 17 00:00:00 2001 From: Chad Dupuis Date: Tue, 16 Aug 2011 11:29:26 -0700 Subject: [PATCH] [SCSI] qla2xxx: Double check for command completion if abort mailbox command fails. Close a small window where we could falsely fail an abort request if the mailbox command fails but the command was returned during interrupt context.
