From dccabfad20880bc6c8be21b538df4293506b99f8 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Fri, 27 Nov 2015 16:31:38 +0100 Subject: [PATCH] btrfs: use smaller type for btrfs_path reada The possible values for reada are all positive and bounded, we can later save some bytes by storing it in u8.
