Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

> Recent kernels seem to generate this:

See Bugzilla for the full thread and attached logs (dmesg, xorg, bisection
log).

Anyway, I'm adding it to regzbot:

#regzbot introduced: 105ff5339f498a https://bugzilla.kernel.org/show_bug.cgi?id=217508
#regzbot title: memfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL on Xorg

Thanks.
