Also skb_release_data(), ___pskb_trim() and __pskb_pull_tail(). Can these
ever perform the final release against a page which is on the LRU?
In interrupt context?

These page releases run from either user or softint context.

They must never run from HW irqs, in fact there is a BUG()
check there against this.

Any page that can be found in the page cache can end up here. So
whatever that mean for "release against a page which is on the LRU"
applies here.
