Subject: [PATCH 2.4] Fix rlimit check in precheck_file_write()
Message-ID: <20041222215759.GA217560@dragonfly.engr.sgi.com>

Sender: linux-kernel-owner@vger.kernel.org
X-Mailing-List: linux-kernel@vger.kernel.org

Remove a broken assumption that rlimits are 32 bits which can cause
nasty things to happen on 64-bit machines if we try to write past the
2^32-1th character of a file and a larger file size limit exists.
