From d8f429e1669b9709f5b669aac9d734dbe0640891 Mon Sep 17 00:00:00 2001 From: Junichi Nomura Date: Fri, 3 Oct 2014 17:27:12 -0400 Subject: block: add bioset_create_nobvec() Users of bio_clone_fast() do not want bios with their own bvecs. Allocating a bvec mempool as part of the bioset intended for such users is a waste of memory. bioset_create_nobvec() creates a bioset that doesn't have the bvec mempool.
