From 3db9d208dd5f30b12900989c6d2214782b8e2011 Mon Sep 17 00:00:00 2001 From: Stafford Horne Date: Wed, 3 Apr 2024 06:40:37 +0100 Subject: misc: Add support for Linux uio.h RWF_NOAPPEND flag In Linux 6.9 a new flag is added to allow for Per-io operations to disable append mode even if a file was opened with the flag O_APPEND. This is done with the new RWF_NOAPPEND flag. This caused two test failures as these tests expected the flag 0x00000020 to be unused. Adding the flag definition now fixes these tests on Linux 6.9 (v6.9-rc1). FAIL: misc/tst-preadvwritev2 FAIL: misc/tst-preadvwritev64v2 This patch adds the flag, adjusts the test and adds details to documentation.
