Re: [NTDEV][WIN2k][WINXP] Use of the ExInterlockedXxxx function calls across different IRQL levels

> Does Windows support Priority Inversion??

That is if one thread holds the lock and it is interrupted by an ISR which
tried to acquire the same lock, then the thread that was holding the lock
is
given pref first to execute and then the ISR is executed.

For ISRs - no. The only lock which can be acquired from the ISR is the
spinlock, which is too simple to implement such things.
