From bdc2491708c47601603918a9a20acddef6e1d814 Mon Sep 17 00:00:00 2001 From: "Dennis Zhou (Facebook)" Date: Tue, 11 Sep 2018 14:41:32 -0400 Subject: blkcg: associate writeback bios with a blkg One of the goals of this series is to remove a separate reference to the css of the bio. This can and should be accessed via bio_blkcg. In this patch, the wbc_init_bio call is changed such that it must be called after a queue has been associated with the bio.
