I really don't have that good a recall of what warning fixes people are
sending, I might notice if I get two versions of the same thing that I
look at at roughly the same time but even with a few hours between it's
most likely that I'll have completely forgotten.  Warning fixes are in
general not memorable, it's not a good sign if they are.  The default
assumption for any warning fix that doesn't say anything else is going
to be that either the issue or the toolchain is very new.

For any kind of fix if you think that things are in some way urgent you
should say something promptly (or provide some indication of this in the
submission if you're sending the fix yourself, such as with a fixes
tag).  If nobody says anything then you should assume that nobody else
is going to be aware of any urgency and that this will affect handling.
Should it happen that things aren't flagged up then of course do so but
consider that this may well be the first time people will be aware
there's any urgency, don't assume that people will have been operating
with information they didn't have.

If it's on the for-5.11 branch then it will be for 5.11, which it must
be if it was applied then.  If it was and it was applied that long ago
it'll already be queued in Takashi's tree and I guess he didn't send it
on yet.
