From bbe339cc323ca9d2a57ac203d2d9d11a09655dcc Mon Sep 17 00:00:00 2001 From: David Sterba Date: Tue, 27 Nov 2018 15:25:13 +0100 Subject: [PATCH] btrfs: drop extra enum initialization where using defaults The first auto-assigned value to enum is 0, we can use that and not initialize all members where the auto-increment does the same. This is used for values that are not part of on-disk format.
