Rainer Weikusat 77b75f4d8c unix: use wq_has_sleeper in unix_dgram_recvmsg ... The current unix_dgram_recvmsg does a wake up for every received datagram. This seems wasteful as only SOCK_DGRAM client sockets in an n:1 association with a server socket will ever wait because of the associated condition. The patch below changes the function such that the wake up only happens if wq_has_sleeper indicates that someone actually wants to be notified. Testing with SOCK_SEQPACKET and SOCK_DGRAM socket seems to confirm that this is an improvment. Signed-Off-By: Rainer Weikusat <rweikusat@mobileactivedefense.com> Signed-off-by: David S.
