Ftrace Function Graph ARM - eLinux.org
This page holds information from Tim Bird's talk at Linux Symposium Montreal (July, 2009), and at ELC Europe and the Japan Linux Symposium (October, 2009). In Canada, Tim talked about patches against the 2.6.31-rc1 kernel tree for adding function graph tracing to the ARM architecture, for the Ftrace system. In France and Japan, Tim talked about patches against 2.6.32-rc5. Presentation Here is the

vflare: Linux kernel workflow with Git
You worked on some part of Linux kernel. It works great. Now, how to generate the patch series and send it out for review? For this, I always used to generate diffs, create a set of draft mails (one for each patch) in KMail or Thunderbird, and send all these mails one-by-one. This workflow quickly became a big headache. Then I learned Git (and some related tools) to do all this from command line a
