Subject: [PATCH 01/16] fix default __strnlen_user macro
Date: Wed, 11 May 2011 16:13:48 -0400	[thread overview]
Message-ID: <1305144843-5058-2-git-send-email-msalter@redhat.com> (raw)
In-Reply-To: <1305144843-5058-1-git-send-email-msalter@redhat.com>

The existing __strnlen_user macro simply resolved to strnlen. However, the
count returned by strnlen_user should include the NULL byte. This patch
fixes the __strnlen_user macro to include the NULL byte in the count.
