>If it has to wait, it will panic. Given that, why do the locking at all?
i assume the intention is along these lines:
it's to allow the use during reset of a given driver's
standard functions that normally must qlock, to avoid requiring two copies
of them, with and without the qlock.
after reset, it's illegal to call qlock without a process (notably
in an interrupt function), as it previously was.
