From e24dcbef93dbbf529fbedfc6ce8ab22d2cef35f0 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 18 Oct 2010 08:33:02 +0200 Subject: shpchp: update workqueue usage * Rename shpchp_wq to shpchp_ordered_wq and add non-ordered shpchp_wq which is used instead of the system workqueue. This is to remove the use of flush_scheduled_work() which is deprecated and scheduled for removal. * With cmwq in place, there's no point in creating workqueues lazily. Create both shpchp_wq and shpchp_ordered_wq upfront. * Include workqueue.h from shpchp.h.
