From 8855438ab64d025495007b941ac75f2078274c13 Mon Sep 17 00:00:00 2001 From: Søren Sandmann Pedersen Date: Sat, 1 Sep 2012 11:13:49 -0400 Subject: Process outstanding commands in the ring after changing capability bits When a new client connects, there may be commands in the ring that it can't understand, so we need to process these before forwarding new commands to the client. By doing this after changing the capability bits we ensure that the new client will never see a command that it doesn't understand (under the assumption that the guest will read and obey the capability bits).
