Description:
In "mysql-6.0-dtrace" all probes which were described in the user manual have been available and working.
In "mysql-next" I am missing the following probes:

read-row-start
read-row-done
index-read-row-start
index-read-row-done

How to repeat:
enable dtrace (configure) and run "test_all_probes.d" (attached) after having started e.g. "./mtr select". Errors will araise. 

Suggested fix:
Port the probes back from 6.0.

dtrace script to test the probes.

Thank you for the report.

Verified as described.

I tried the probes with "mysql-next-mr" and all probes were available. As it cannot more reproduced I set the status to "can't repeat".
