From 2e17c7c65e5dcbb53a6384a3406244f62bca189c Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 26 Aug 2013 16:53:15 -0400 Subject: Btrfs: add support for asserts One of the complaints we get a lot is how many BUG_ON()'s we have. So to help with this I'm introducing a kconfig option to enable/disable a new ASSERT() mechanism much like what XFS does. This will allow us developers to still get our nice panics but allow users/distros to compile them out. With this we can go through and convert any BUG_ON()'s that we have to catch actual programming mistakes to the new ASSERT() and then fix everybody else to return errors. This will also allow developers to leave sanity checks in their new code to make sure we don't trip over problems while testing stuff and vetting new features.
