Lu" To: "H. Peter Anvin" , LKML Subject: [PATCH] Use __kernel_long_t in struct msgbuf Message-ID: <20131225155850.GA26252@gmail.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.5.21 (2010-09-15) Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org X32 msgsnd/msgrcv system calls are the same as x86-64 msgsnd/msgrcv system calls, which use 64-bit integer for long in struct msgbuf . But x32 long is 32 bit. This patch replaces long in struct msgbuf with __kernel_long_t. Signed-off-by: H.J.
