From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yury Norov Subject: [PATCH 01/19] compat ABI: use non-compat openat and open_by_handle_at variants Date: Sat, 18 Jun 2016 02:54:10 +0300 Message-ID: <1466207668-10549-2-git-send-email-ynorov@caviumnetworks.com> References: <1466207668-10549-1-git-send-email-ynorov@caviumnetworks.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: List-Unsubscribe: List-Subscribe: List-Archive: List-Post: List-Help: , Sender: libc-alpha-owner@sourceware.org In-Reply-To: <1466207668-10549-1-git-send-email-ynorov@caviumnetworks.com> To: arnd@arndb.de, catalin.marinas@arm.com, linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org, linux-doc@vger.kernel.org, linux-arch@vger.kernel.org, libc-alpha@sourceware.org Cc: schwidefsky@de.ibm.com, heiko.carstens@de.ibm.com, ynorov@caviumnetworks.com, pinskia@gmail.com, broonie@kernel.org, joseph@codesourcery.com, christoph.muellner@theobroma-systems.com, bamvor.zhangjian@huawei.com, szabolcs.nagy@arm.com, klimov.linux@gmail.com, Nathan_Lynch@mentor.com, agraf@suse.de, Prasun.Kapoor@caviumnetworks.com, kilobyte@angband.pl, geert@linux-m68k.org, philipp.tomsich@theobroma-systems.com, manuel.montezelo@gmail.com, linyongting@huawei.com, maxim.kuvyrkov@linaro.org, davem@davemloft.net List-Id: linux-arch.vger.kernel.org The only difference is that non-compat version forces O_LARGEFILE, and it should be the default behaviour for all architectures, as we don't support 32-bit off_t. The only exception is tile32, that continues with compat version of syscalls.
