This patch is already included since glibc 2.28-8 as part of pulling the
upstream stable branch. So it should already be fixed in buster, bullseye
and sid.

At least I confirm that the bug23844.wr.c testcase from the upstream bug
report sometimes fail with glibc 2.28-7, but never fails with glibc
2.28-8.
