Date: Thu, 18 Dec 2008 12:42:19 +0100 Message-Id: <1229600542-11585-1-git-send-email-kraxel@redhat.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi folks, Guess I have your attention now thanks to LWN ;) Next round of the preadv & pwritev patch series, hopefully finally solving the architecture issues. I've decided to go with the suggestion from the s390 guys: split the 64bit offset into two explicitly coded 32bit halves. The syscall prototype should work now for all archs without (in-kernel) wrappers. glibc must wrap the syscalls though to hide that split from the applications. But there is no way around glibc wrappers anyway, so I think that is sensible decision. cheers, Gerd
