Li RongQing 304db6cb76 page_pool: refill page when alloc.count of pool is zero ... "do {} while" in page_pool_refill_alloc_cache will always refill page once whether refill is true or false, and whether alloc.count of pool is less than PP_ALLOC_CACHE_REFILL or not this is wrong, and will cause overflow of pool->alloc.cache the caller of __page_pool_get_cached should provide guarantee that pool->alloc.cache is safe to access, so in_serving_softirq should be removed as suggested by Jesper Dangaard Brouer in https://patchwork.ozlabs.org/patch/1233713/ so fix this issue by calling page_pool_refill_alloc_cache() only when pool->alloc.count is zero Fixes: 44768decb7 ("page_pool: handle page recycle for NUMA_NO_NODE condition") Signed-off-by: Li RongQing <lirongqing@baidu.com> Suggested-by: Jesper Dangaard Brouer <brouer@redhat.com> Acked-by: Jesper Dangaard Brouer <brouer@redhat.com> Acked-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: David S.
