Re: [v3 net-next 08/10] skbuff: reuse NAPI skb cache on allocation path (__build_skb())

we're in such context. This includes: build_skb() (called only

(called from the same place or from kernel network softirq
functions).

build_skb is called from sleepable context in drivers/net/tun.c .
Perhaps there are other cases.
