Subject: [PATCH net-next 0/2] xsk: mitigate the side effect of cq_lock

From: Jason Xing <kernelxing@...cent.com>

Two optimizations regarding cq_lock can yield a performance increase
because of avoiding disabling and enabling interrupts frequently.

Jason Xing (2):
  xsk: avoid using heavy lock when the pool is not shared
  xsk: use a smaller new lock for shared pool case
