This patch needs a better description than "bug", and you forgot to cc
the linux-user maintainer. The patch should describe what it touches
(linux-user), what it does, what for and make clear why that is correct.
Is there a particular test case that's broken without the patch?

I can't speak for Stefan, but to me it is totally unclear from looking
at the patch what sas_ss_flags() does here so this is likely not really
a trivial one.
