Open Source Summit Europe + ELC Europe 2017

Ftrace is the official tracer of the Linux kernel. It's been a while since I last talked about what is in ftrace. But I haven't stopped developing more features. This talk will give a very brief overview of a intro to ftrace, but then focus on what has been added in the last few years. There's multiple instance, a new file system to mount it on, stack tracing, variable per cpu buffer sizes, better tracing of forked process, and much more. Most of this is document in the kernel documentation, but I find very few people read that. This talk will have lots of demos, to see how to actual use tracing for those that prefer action over reading about the action.
