dm-crypt: fix warning in shutdown path
The counter for the number of allocated pages includes pages in the mempool's reserve, so checking that the number of allocated pages is 0 needs to happen after we exit the mempool. Fixes: 6f1c819c219f ("dm: convert to bioset_init()/mempool_init()") Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Reported-by: Krzysztof Kozlowski <krzk@kernel.org> Acked-by: Mike Snitzer <snitzer@redhat.com> Fixed to always just use percpu_counter_sum() Signed-off-by: Jens Axboe <axboe@kernel.dk>
