Ah, TIL - thanks for that tip! But I still think it would be good to have a 
complete documentation of the perf.data file format in one place. I guess 
patches would be welcome to add more aspects of the file format there, even if 
it's generated by the kernel? That helps for thirdparty tools that parse the 
perf.data files (like perfparser used by QtCreator and hotspot).

Cheers
