I'd like to see a more desriptive title than this. Maybe "memfd_luo:
various fixes and cleanups". This isn't a big deal and "Modify
memfd_luo code" is good enough ;)

OK, I'll add this. I'm trying to seriously slow things down now but
this series does address a bunch of issues.

Maintainers, there are a few more patches here than were in v2, so
please take a look?

Thanks.
