Re: [PATCH 5/5] perf report: Support callchains with relativeoverhead rate

[Ingo Molnar]

btw., i get some buggy looking output with:

  $ perf record -f -g ~/hackbench 10

  $ perf report -c


                |--5.11%-- unix_stream_sendmsg
                |          |          
                |          |--100.00%-- __sock_sendmsg
                |          |          sock_aio_write
                |          |          do_sync_write
                |          |          vfs_write
                |          |          sys_write
                |          |          sysenter_dispatch
                |          |          0xf7f72430
                |          |          0xffebbca000000014
                |          |          
                |           --11.11%-- sock_aio_write
                |                     do_sync_write
                |                     vfs_write
                |                     sys_write
                |                     sysenter_dispatch
                |                     0xf7f72430
                |                     0xffebbca000000014

Those percentages dont sum up to 100% :-)

Another detail: i think we should signal when we crop the output due 
to the filter, via a line of:

                |          [...]

or so.

Plus, when doing 'perf report' on a call-chain recording, shouldnt 
we auto-detect this fact and default to fractal output 
automatically, instead of flat mode?

User can still force flat mode via 'perf report -c flat'.
