Re: [PATCH] mm: msync: require either MS_ASYNC or MS_SYNC

Hi!

quoted

and there's no good
reason to believe that this behavior would have persisted
indefinitely.

The msync(2) man page (as currently written in man-pages.git) is
silent on the behavior if both flags are unset, so this change should
not break an application written by somone who carefully reads the
Linux man pages or the POSIX spec.

Sadly, people do not always carefully read man pages, so there
remains the chance that a change like this will break applications.
Aside from standards conformance, what do you see as the benefit
of the change?

I've looked around Linux Test Project and this change will break a few
testcases, but nothing that couldn't be easily fixed.

The rest of the world may be more problematic though.
