Ooh, ouch, definitely.  We should clear that.  Can you please make a
patch?

Sure... but what do you think is better?

I'd prefer to simply clear PF_NOFREEZE (without set_freezable), but
obviously this doesn't look exactly right from cgroup_freezer pov.

I don't think it matters all that much.  It's a pretty special case.
Maybe define PF_CLEAR_ON_EXEC_MASK or something and just include
PF_NOFREEZE in it?

Thanks.
