I check latest CentOS Stream 8 kernel version 4.18.0-269.el8.x86_64
- this regression with broken nspawn containers still present here.

Does any chance exist that this kernel regression will be fixed
in CentOS Stream 8 before CentOS 8.4 / RHEL 8.4 will be released?

Thank you! Now I can download source - but all patches are merged
into one file linux-4.18.0-269.el8.tar.xz - I have no chances
to find which patch to the kernel source tree causes this regression
with broken systemd-nspawn containers. As I understand, only Red Hat
kernel developers now can find the root cause of regression and fix it.

And all I can do is file a bug
https://bugzilla.redhat.com/show_bug.cgi?id=1913806
and hope for the best?
