[PATCH bpf-next v3 2/4] net: page_pool, skbuff: make skb_mark_for_recycle() always available

From: Alexander Lobakin
Date: Mon Mar 13 2023 - 17:57:23 EST


skb_mark_for_recycle() is guarded with CONFIG_PAGE_POOL, this creates
unneeded complication when using it in the generic code. For now, it's
only used in the drivers always selecting Page Pool, so this works.
Move the guards so that preprocessor will cut out only the operation
itself and the function will still be a noop on !PAGE_POOL systems,
but available there as well.
No functional changes.
