But i see that if receiver does not reply for one thread then other threads on sender will also stay in block state. 2) To fix this, i have released the IO lock just before polling and after polling acquiring it back. (using KDBUS as transport). But i see comment that IO lock is not delibrately removed. Any specific reasons for this?
