From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tina Ruchandani Subject: [PATCH] drm/exynos/ipp: Replace struct timeval usage Date: Mon, 1 Jun 2015 09:09:00 +0530 Message-ID: <20150601033859.GA3254@tinar> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Received: from mail-pa0-f50.google.com ([209.85.220.50]:35893 "EHLO mail-pa0-f50.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1754529AbbFADjF (ORCPT ); Sun, 31 May 2015 23:39:05 -0400 Received: by pacux9 with SMTP id ux9so59442275pac.3 for ; Sun, 31 May 2015 20:39:04 -0700 (PDT) Content-Disposition: inline Sender: linux-samsung-soc-owner@vger.kernel.org List-Id: linux-samsung-soc@vger.kernel.org To: Arnd Bergmann Cc: Inki Dae , Joonyoung Shim , Seung-Woo Kim , Kyungmin Park , linux-samsung-soc@vger.kernel.org, linux-arm-kernel@lists.infradead.org, y2038@lists.linaro.org 'struct timeval' uses a 32-bit seconds representation which will overflow in the year 2038 and beyond. This patch replaces the use of struct timeval with struct timespec64 which uses a 64-bit seconds representation and is y2038 safe. The patch is part of a larger effort to remove all 32-bit timekeeping variables (timeval, time_t and timespec) from the kernel.
