+Subject: [PATCH 2/2] 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.
