-Subject: [PATCH] net: page_pool: use in_softirq() instead
-
-We use BH context only for synchronization, so we don't care if it's
-actually serving softirq or not.
-
-As a side node, in case of threaded NAPI, in_serving_softirq() will
-return false because it's in process context with BH off, making
-page_pool_recycle_in_cache() unreachable.
