Subject: [PATCH 3/5] 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).
