This patchset aims to remove the bh-safe locks on the client side.
At this time it should be seen as a toy/strawman effort in order to
help the community figure out whether or not there are setups out
there that are actually seeing performance bottlenecks resulting
from taking bh-safe locks inside other spinlocks.
Trond Myklebust (5):
SUNRPC: Replace the queue timer with a delayed work function
SUNRPC: Replace direct task wakeups from softirq context
SUNRPC: Remove the bh-safe lock requirement on xprt->transport_lock
SUNRPC: Remove the bh-safe lock requirement on the
rpc_wait_queue->lock
SUNRPC: Reduce the priority of the xprtiod queue
