From 2c275afeb61dab732353aae2c7de01b6a87dcefc Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 27 Mar 2023 09:49:53 +0900 Subject: block: make blkcg_punt_bio_submit optional Guard all the code to punt bios to a per-cgroup submission helper by a new CONFIG_BLK_CGROUP_PUNT_BIO symbol that is selected by btrfs. This way non-btrfs kernel builds don't need to have this code.
