#     sbitmap: Protect swap_lock from softirqs
#     
#     The swap_lock used by sbitmap has a chain with locks taken from softirq,
#     but the swap_lock is not protected from being preempted by softirqs.
#     
#     A chain exists of:
#     
#      sbq->ws[i].wait -> dispatch_wait_lock -> swap_lock
#     
#     Where the sbq->ws[i].wait lock can be taken from softirq context, which
#     means all locks below it in the chain must also be protected from
#     softirqs.
#
