Subject: [RFC PATCH bpf-next v2 01/17] net: refactor net assignment for seq_net_private structure
Date: Wed, 15 Apr 2020 12:27:40 -0700 [thread overview]
Message-ID: <20200415192740.4082720-1-yhs@fb.com> (raw)
In-Reply-To: <20200415192740.4082659-1-yhs@fb.com>
Refactor assignment of "net" in seq_net_private structure
in proc_net.c to a helper function. The helper later will
be used by bpfdump.
