oops, make that this instead:


commit b3a63d0c17e6e1d23a6b44502b55f066adfd8e6a
Author: Arnaldo Carvalho de Melo <acme@redhat.com>
Date:   Tue May 5 13:33:12 2020 -0300

    perf flamegraph: Use /bin/bash for report and record scripts
    
    As all the other tools/perf/scripts/python/bin/*-{report,record}
    scripts, fixing the this problem reported by Daniel Diaz:
    
      Our OpenEmbedded builds detected an issue with 5287f9269206 ("perf
      script: Add flamegraph.py script"):
        ERROR: perf-1.0-r9 do_package_qa: QA Issue:
      /usr/libexec/perf-core/scripts/python/bin/flamegraph-report contained
      in package perf-python requires /usr/bin/sh, but no providers found in
      RDEPENDS_perf-python? [file-rdeps]
    
      This means that there is a new binary pulled in in the shebang line
      which was unaccounted for: `/usr/bin/sh`. I don't see any other usage
      of /usr/bin/sh in the kernel tree (does not even exist on my Ubuntu
      dev machine) but plenty of /bin/sh. This patch is needed:
