I can see why that would raise eyebrows. I can see getting bashed
mercilessly with interrupt latency concerns as a result here. Can you
suggest any defenses?

Hi Ingo,
I'm seeing an LTP test fail for ltp test sigaction_16_24. Basically,
it tests whether the SA_RESTART flag works for the sem_wait operation.
I see sem_wait is implemented with futex_wait, so I wonder whether we
can make it restartable? Am I going about it the right way? (Seems to

Perhaps so something with PAGE_SIZE here, as you know there are
platforms/configs where PAGE_SIZE != 4k :-)
Any allocation 2k just uses a regular allocation which will waste space.

If you want to cast a pointer to a small value then start by turning it
into an unsigned long so the compiler knows what is going on.
Personally I find the whole approach used by this driver for types of
registers (which are really USB register numbers) utterly perverse...

Point well taken. A revised patch with your suggested fix is below.
The really nice solution IMHO, would be to remove the print_symbol and
