From abd30bb0af9d4671506502278e8631bed9e3c35c Mon Sep 17 00:00:00 2001 From: Tsutomu Itoh Date: Mon, 24 Jan 2011 00:57:10 +0000 Subject: [PATCH] btrfs: check return value of btrfs_start_ioctl_transaction() properly btrfs_start_ioctl_transaction() returns ERR_PTR(), not NULL. So, it is necessary to use IS_ERR() to check the return value.
