[RFC PATCH v3 8/9] vmci/vsock: check SO_RCVLOWAT before wake up reader

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This adds extra condition to wake up data reader: do it only when number
of readable bytes >= SO_RCVLOWAT. Otherwise, there is no sense to kick
user,because it will wait until SO_RCVLOWAT bytes will be dequeued.
