Subject: [PATCH RFC 0/3] perf script: Add callindent option

Hi

Andi Kleen sent a couple of patches to add a callindent option to
perf script. If Andi is agreeable, I would like to propose an
alternative implementation.

While there are some differences in the resulting output, the main
differences are:

 1. Tell the decoder to feed branches to the thread stack, which has the
 advantage that it happens before branch filtering and so can be used
 with different itrace options (e.g. it still works when only showing
 calls, even though the thread stack needs to see calls and returns). Also
 it does not conflict with using the thread stack to get callchains.

 2. Print "call" or "ret" instead of using a different event

Adrian Hunter (3):
      perf: script: Fix documentation of '-f' when it should be '-F'
      perf auxtrace: Add option to feed branches to the thread stack
      perf script: Add callindent option
