you are not referring to the 'synchronous wakeups' as used by fs/pipe.c, right? in_interrupt() isolates interrupt-context wakeups (asynchronous wakeups) and process-context wakeups - which can also be called synchronous, in a way.
so i think your current patch should cover unix domain sockets just as well, they certain dont use IRQ-context wakeups.
