Subject: [PATCH 5/6] block: move three bvec helpers declaration into private helper
Date: Wed, 30 Dec 2020 08:32:54 +0800 [thread overview]
Message-ID: <20201230003255.3450874-6-ming.lei@redhat.com> (raw)
In-Reply-To: <20201230003255.3450874-1-ming.lei@redhat.com>
bvec_alloc(), bvec_free() and bvec_nr_vecs() are only used inside block
layer core functions, no need to declare them in public header.
