From b8acb808468a88a188d7c5aba3681c583a5785f9 Mon Sep 17 00:00:00 2001 From: Max Asbock Date: Tue, 21 Jun 2005 17:16:33 -0700 Subject: [PATCH] ibmasm driver: correctly wake up sleeping threads Due to my incomplete understanding of the wait_event_interruptible() function threads waiting for service processor events were not woken up. This patch fixes that problem.
