From 2bcbc81421c511ef117cadcf0bee9c4340e68db0 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Wed, 27 Apr 2016 10:48:52 +0200 Subject: [PATCH] qla1280: Don't allocate 512kb of host tags The qla1280 driver sets the scsi_host_template's can_queue field to 0xfffff which results in an allocation failure when allocating the block layer tags for the driver's queues. This was introduced with the change for host wide tags in commit 64d513ac31b - "scsi: use host wide tags by default". Reduce can_queue to MAX_OUTSTANDING_COMMANDS (512) to solve the allocation error.
