Gregg: DTrace for Linux 2016

Brendan Gregg celebratesthe capabilities of Linux kernel tracing with BPF. "With thefinal major capability for BPF tracing (timed sampling) merging in Linux4.9-rc1, the Linux kernel now has raw capabilities similar to thoseprovided by DTrace, the advanced tracer from Solaris. As a long time DTraceuser and expert, this is an exciting milestone! On Linux, you can nowanalyze the performance of applications and the kernel usingproduction-safe low-overhead custom tracing, with latency histograms,frequency counts, and more."
