It fixes a specific case of non-devtmpfs + the loop device returned by
loop-control does not exist in /dev yet. The code after in that case is
racy and buggy, but such a combo is rare, probably just us, so we didn't
submit it.

I sent this a long time ago and it was rejected.

This silences very loud kernel complaints when using compressed modules
IIRC. Was discussed on both here and lkml.

Without it modules behind a symlinked dir aren't found; but again, very
likely just affects TC, so didn't send it.
