From 32ae763e3fce4192cd008956a340353a2e5c3192 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Thu, 5 Mar 2009 14:46:03 -0600 Subject: [SCSI] iscsi lib: have lib create work queue for transmitting IO We were using the shost work queue which ended up being a little akward since all iscsi hosts need a thread for scanning, but only drivers hooked into libiscsi need a workqueue for transmitting. So this patch moves the xmit workqueue to the lib.
