Hi all,
this patch introduces a regression in some versions of qemu-aarch64 (at least as built by debian): https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1087822
It doesn't look like it still is a problem with newer versions of qemu so I'm not sure if this should be reverted on master, but it took me a bit of time to track this down to this commit as my reproducer isn't great, so it might make sense to revert this commit on stable branches?
(I don't remember the policies on "don't break userspace", but qemu-user is a bit of a special case here so I'll leave that up to Greg)
I've confirmed that this bug occurs on top of the latest v6.1.118 and goes away reverting this. (I've also checked the problem also occurs on master and reverting the patch also works around the issue there at this point)
Interestigly there is another report in Debian which identifies the backport of upstream commit 44c76825d6eefee9eb7ce06c38e1a6632ac7eb7d to cause issues in the 6.1.y series:
