Hi Clark,
As you have indicated on IRQ you like to test the swait patches on how
it performs with -rt. Here is the backport of the swait v3 patch set.
In order to test these patches here drop following patches from
the 4.1.10-rt10 tree:
wait-simple-implementation.patch
work-simple-Simple-work-queue-implemenation.patch
rcu-more-swait-conversions.patch
completion-use-simple-wait-queues.patch
block-blk-mq-use-swait.patch
KVM-use-simple-waitqueue-for-vcpu-wq.patch
and apply the patche from this patch set. My test box is running since
one hour without crashing. hackbench, cyclictest, kernel build
and KVM torture running inside a KVM.
Daniel Wagner (2):
work-simple: Simple work queue implemenation
rcu: Do not call rcu_nocb_gp_cleanup() while holding rnp->lock
Marcelo Tosatti (1):
KVM: use simple waitqueue for vcpu->wq
Paul Gortmaker (1):
rcu: use simple wait queues where possible in rcutree
Peter Zijlstra (Intel) (1):
wait.[ch]: Introduce the simple waitqueue (swait) implementation
Sebastian Andrzej Siewior (1):
block: blk-mq: Use swait
Thomas Gleixner (1):
completion: Use simple wait queues
