From 8fdf30d5429605a4c30cc515c73e5eab140035de Mon Sep 17 00:00:00 2001 From: Christof Schmitt Date: Mon, 2 Mar 2009 13:09:01 +0100 Subject: [SCSI] zfcp: Send ELS ADISC from workqueue Issue ELS ADISC requests from workqueue. This allows the link test request to be sent when the request queue is full due to I/O load for other remote ports. It also simplifies request queue locking, zfcp_fsf_send_fcp_command_task is now the only function that has interrupts disabled from the caller. This is also a prereq for the FC passthrough support that issues ELS requests from userspace.
