From c821e7f3daa4d02d6303f4f97a3243ea8a6f9411 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Fri, 2 Jun 2017 18:35:36 +0200 Subject: [PATCH] btrfs: pass bytes to btrfs_bio_alloc Most callers of btrfs_bio_alloc convert from bytes to sectors. Hide that in the helper and simplify the logic in the callsers.
