From ad9b8399537670a990572c4b0c4da5411e3b68cf Mon Sep 17 00:00:00 2001
From: Sam James <sam@gentoo.org>
Date: Sat, 5 Aug 2023 00:04:33 +0100
Subject: [PATCH 09/12] sysdeps: tst-bz21269: handle ENOSYS & skip
appropriately
SYS_modify_ldt requires CONFIG_MODIFY_LDT_SYSCALL to be set in the kernel, which
some distributions may disable for hardening. Check if that's the case (unset)
and mark the test as UNSUPPORTED if so.
Reviewed-by: DJ Delorie <dj@redhat.com>
Signed-off-by: Sam James <sam@gentoo.org>
(cherry picked from commit 652b9fdb77d9fd056d4dd26dad2c14142768ab49)
