From 37252a66f34940421942725ca75d12e6008682dc Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Thu, 31 Jan 2013 00:54:58 +0000 Subject: [PATCH] btrfs: fix varargs in __btrfs_std_error __btrfs_std_error didn't always properly call va_end, and might call va_start even if fmt was NULL. Move all the varargs handling into the block where we have fmt.
