From 3a58417486ca99a3bfef40e309f38adb45a5171d Mon Sep 17 00:00:00 2001 From: Lu Fengqi Date: Sat, 4 Aug 2018 21:10:55 +0800 Subject: [PATCH] btrfs: switch update_size to bool in btrfs_block_rsv_migrate and btrfs_rsv_add_bytes Using true and false here is closer to the expected semantic than using 0 and 1. No functional change.
