AFAICS the proposed patch is totally safe; it can't make things worse,
and should save some cycles to boot. Whether it fixes what you're
seeing is a different question of course, but testing would be mighty
helpful for that.

What I would actually ask about as far as production risk goes is
whether you are accustomed to building from patched sources. If you're
not, the risk of dropping a stitch in the build process could be
significant.
