I had assumed that the long term direction was to use tracepoints,
which also has the advantage of not requiring kernels built with
CONFIG_EXT4_DEBUG.
Hmm.... one thing though is if we want bug reporters to use
tracepoints (as opposed to just developers), we'll need to have some
pre-made shell scripts to make it easy for non-developers to enable
tracepoints for various problems.
