malloc, VFS read/write, and block I/O flame graphs

Brendan Gregg


For reference, I created a few bcc/BPF tools that generate data for
these flame graphs. The tools are based on the offcputime code, and

Examples of using them can be found on:

I'm not going to submit them to bcc, since I think they are too
special-case and would subtract value from bcc (due to clutter) rather
than add to it. Plus there's a lot of duplicated code. So I'll leave
them in my BPF-tools repo.
