Subject: [PATCH 1/2] debugfs.c: the max length of debugfs argument is too short
Date: Fri, 19 Jul 2013 10:17:36 +0800	[thread overview]
Message-ID: <1374200257-2873-2-git-send-email-liezhi.yang@windriver.com> (raw)
In-Reply-To: <1374200257-2873-1-git-send-email-liezhi.yang@windriver.com>

The max length of debugfs argument is 256 which is too short, the
arguments are two paths, the PATH_MAX is 4096 according to
/usr/include/linux/limits.h, use 2048 (4096 / 2) is a reasonable value.
