SubjectRe: [PATCH v2 1/5] fs: Add support for an O_MAYEXEC flag on sys_open()

Isn't that desirable anyway because otherwise fcntl with F_GETFL will
give really confusing results?

I see us rather doing the opposite, i.e. implement openat2 with
non-exotic flags using openat. But we've bitten by this in the past, so
maybe that's not such a great idea. It's tempting to make the same
mistake again for every new system call.

Thanks,
Florian
