====== Meeting 28 April 2016 ======

Mark Johnston, Shrikanth Kamath, Erin %%MacNeil%%, George Neville-Neil

  * DTrace man pages don't show up in the on-line version

  * George mentions the new random() function that's not yet shared outside CADETS.

  * Enabling the destructive action using a copyout may or may not work.

  * Static functions are not showing their arguments properly. Mark says that this may be compiler related.

  * Tracing a 32 bit application on a 64 bit system causes the application to crash.  Mark says he knows about this and will try to track it down before 11.0

  * Add a bsd:::: provider and move mbuf under that.

  * We discussed the performance of aggregators but it seems that there isn't much to do immediately about that.

  * Mark has measured his new SDT patch and it improves performance by 2% which matters because turning on KDTRACE does impact performance by about 2%.  He will work to get this in soon.

  * Mark has been looking at the conversion of CTF tools from Joyent which can deal with CTF and DWARF more naturally.

  * Bryan Cantril has announced (on Twitter) a %%DTraceConf%% on May 25 but there are as yet no details.
