From f48bf7fb00f74d93105ba69522a3f6c9435d6af3 Mon Sep 17 00:00:00 2001 From: Christof Schmitt Date: Thu, 21 Aug 2008 13:43:34 +0200 Subject: [PATCH] [SCSI] zfcp: Simplify ccw notify handler The notify handler does not change the list of adapters, it only triggers erp actions to open or shutdown the adapter. We don't need to hold the config semaphore and wait for the erp to complete. This is a prerequisite for a fix in the s390 common i/o code.
