Hi Jamal,
I've been (slowly) working on resurrecting the original design
of my multiqueue patches to address this exact issue of the queue_lock
being a hot item. I added a queue_lock to each queue in the subqueue
struct, and in the enqueue and dequeue, just lock that queue instead of
the global device queue_lock. The only two issues to overcome are the
QDISC_RUNNING state flag, since that also serializes entry into the
qdisc_restart() function, and the qdisc statistics maintenance, which
needs to be serialized. Do you think this work along with your patch
will benefit from one another? I apologize for not having working
patches right now, but I am working on them slowly as I have some blips
of spare time.
Thanks,
-PJ Waskiewicz
