Peter Anvin" Subject: [PATCH v3 0/6] [RFC] copy_strtok_from_user Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Changes in v3: - created strtok_r for kernel. - Simplified copy_strtok_from_user by using strtok_r - updated the rest of the code to handle the above changes I tested both the strtok_r and copy_strtok_from_user with this user app: http://www.kernel.org/pub/linux/kernel/people/rostedt/copy_strtok_from_user.c Results of the test are here: http://www.kernel.org/pub/linux/kernel/people/rostedt/copy_strtok_test.txt I added a "#undef strtok_r" after the strtok_r function and ran it again to make sure the output was still the same, and it was. Andrew, If this version is fine with you, could you ack the patches that create the strtok_r and copy_strtok_from_user functions.
