I really think this is a horrible hack.

It's basically the kernel giving up, and relying on user space to give
a single flag, and it's broken nasty crap.  Worse, it's broken nasty
crap with a user interface, so we'll be stuck with it forever. Please
no.

What are the drivers that need this, and why can't those drivers just
be fixed to not do braindead things?
