From d4417e22551377c6e589c15ff2b931610e5230bc Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Mon, 16 Oct 2017 16:48:40 +0300 Subject: [PATCH] btrfs: Replace opencoded sizes with their symbolic constants Currently btrfs' code uses a mix of opencoded sizes and defines from sizes.h. Let's unifiy the code base to always use the symbolic constants.
