[GIT PULL] uml-for-6.17-rc7

[Johannes Berg]

Hi Linus,

So we still have a couple of fixes for ARCH=um, which I'd
meant to send earlier but then forgot. All of them are
pretty long-standing issues that are either not really
happening (the UAF), in rarely used code (the FD buffer
issue), or an issue only for some host configurations
(the executable stack.)

Please pull and let us know if there's any problem.

Thanks,
johannes
