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. # # Reported-by: Clark Williams # Fixes: 58ab5e32e6fd ("sbitmap: silence bogus lockdep IRQ warning") # Fixes: ea86ea2cdced ("sbitmap: amortize cost of clearing bits") # Cc:
