From 7d0d2d385ca7cc511f7d1c64735a1b4aaefd9a1b Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Thu, 29 Apr 2010 14:40:53 +0200 Subject: padata: Remove superfluous might_sleep might_sleep() was placed before mutex_lock() in some places. We remove them because mutex_lock() does might_sleep() too.
