Subject: [PATCH 2/5] debugfs: return directly if failed to allocate memory in debug_fill_super()
Date: Sat, 27 Oct 2012 16:05:26 +0800	[thread overview]
Message-ID: <1351325129-10097-2-git-send-email-clouds.yan@gmail.com> (raw)
In-Reply-To: <1351325129-10097-1-git-send-email-clouds.yan@gmail.com>

If kzalloc failed, memory is not allocated, sb->s_fs_info is NULL.
No need to go through clean up code, return -ENOMEM directly.
