Subject: [PATCH v2 09/21] libtracefs: Add line number and index to expr structure
From: "Steven Rostedt (VMware)" <rostedt@...dmis.org>
In order to have better error messages, record the line number and index
when an expr structure is created. Then this can be used to show where in
the SQL sequence a problem was found if the building of the synth event
has issues.
