[PATCH 0/6] tracing: trace event error_log and inter-event bugfixes

[Tom Zanussi]

Hi Steve,

Here are a few patches that should be applied on top of the
'Inter-event (e.g. latency) support v9' patchset.

The first fixes another problem I noticed when printing flags.

The rest implement the tracing/events/error_log suggested by Masami,
and update the inter-event code to use it (and remove the old hist
file error mechanism).

Thanks,

Tom
