To be clear: that concern/question was prompted from having taken a
quick glance at lwn's kernel summit "KS2010: ABI status for tracepoints"
coverage: http://lwn.net/Articles/412685/

But in that article it clearly states:
"there are to be no stable tracepoints in drivers or filesystems".

Not sure where that leaves tracepoints for the block layer.  Anyway,
seems tracepoint kABI is likely a concern for the future (not the
immediate future).

So this change would be nice to get in before there is a new tracepoint
kABI-aware sheriff in town.
