Looking at this again, I see that PQI_RESERVED_IO_SLOTS_SYNCHRONOUS_REQUESTS
is '3', so this is in fact a counting semaphore rather than a mutex,
and the conversion is changing the behavior.
The patch can't go in unless you either show that it should be
a normal mutex rather than a counting semaphore, or you find a way
to keep the behavior the same.
