Re: [PATCH] perf report: auto-detect branch stack sampling mode

[Ingo Molnar]

Another usability bug of the new branch sampling feature is that 
typing the obvious:

  $ perf record -b ./myprog

does not do the obvious thing and default to 'any' but throws a 
*very* unhelpful generic perf error:

 usage: perf record [<options>] [<command>]
    or: perf record [<options>] -- <command> [<options>]

 ...

Really, we should do better than this. Only people who *want* to 
specify finer LBR filters should be forced to specify them.

Thanks,

	Ingo
