Umm. Look at my patch again. It masks the O_CLOEXEC bit *exactly*
because the bit is useless as it is now.

Which is why your previous objection was so silly too and I didn't
even bother replying to the blather. O_CLOEXEC at open time has no
special magical meaning. The only meaningful value for that bit is the
current one.

Which is exactly what my patch did.

How about you just read the patch again?

This issue is closed as far as I am concerned. I repeat from my previous email:

  "I'm not going to commit it, but if others think this is a reasonable
   thing to do and remind me during the next merge window, we can
   do it then."

Gaah.
