From 94e4e153b1c25a49b4953c424e6e2f66efb449f3 Mon Sep 17 00:00:00 2001 From: Gao Xiang Date: Wed, 4 Sep 2019 10:09:04 +0800 Subject: erofs: kill __submit_bio() As Christoph pointed out [1], " Why is there __submit_bio which really just obsfucates what is going on? Also why is __submit_bio using bio_set_op_attrs instead of opencode it as the comment right next to it asks you to? " Let's use submit_bio directly instead.
