From 930b09072977583226a05b4f2e1db259f9a2417b Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Mon, 25 Mar 2019 14:31:26 +0200 Subject: btrfs: Introduce new bits for device allocation tree Rather than hijacking the existing defines let's just define new bits, with more descriptive names. Instead of using yet more (currently at 18) bits for the new flags, use the fact those flags will be specific to the device allocation tree so define them using existing EXTENT_* flags.
