[PATCH net-next v2 1/1] sfc: replace spinlocks with bit ops for busy poll locking

2015-10-26 Thread Shradha Shah
From: Bert Kenward This patch reduces the overhead of locking for busy poll. Previously the state was protected by a lock, whereas now it's manipulated solely with atomic operations. Signed-off-by: Shradha Shah --- drivers/net/ethernet/sfc/efx.c
