pserialize & hw interrupt

[Ryota Ozaki <ozaki-r%netbsd.org@localhost>]

Hi,

Can we use pserialize for readers in hardware interrupt?
If we use splhigh instead of splsoftserial (pserialize_read_enter)
for critical sections of the readers, we can guarantee that
the readers don't touch a removed object anymore after
pserialize_perform. It this correct?

Thanks,
