[PATCH v1 1/3] perf record: enable LBR callstack capture jointly with thread stack

[Alexey Budankov]

Enable '-j stack' applicability together with '--call-graph dwarf'
option so thread stack data and LBR call stack could be captured 
jointly:

  $ perf record -g --call-graph dwarf,1024 -j stack,u -- stack_test
