From e2690695ce5085677b84fbf2e38d2ed57cad39cd Mon Sep 17 00:00:00 2001 From: Peter Huewe Date: Sun, 15 Apr 2012 02:20:27 +0200 Subject: fuse: Convert to kstrtoul_from_user This patch replaces the code for getting an number from a userspace buffer by a simple call to kstroul_from_user. This makes it easier to read and less error prone.
