# 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 <williams@redhat.com> # Fixes: 58ab5e32e6fd ("sbitmap: silence bogus lockdep IRQ warning") # Fixes: ea86ea2cdced ("sbitmap: amortize cost of clearing bits") # Cc: Jens Axboe <axboe@kernel.dk> # Cc: Ming Lei <ming.lei@redhat.com> #
