Hi,
perf archive has some waring messages, is this a bug?
root@intel-s3e36-01 perf]# ./perf-archive
tar: .build-id/b2/370e39ea2898c6e11c188e2f3879e4e3d6d1ef: Cannot stat: No such file or directory
tar: .build-id/b2/370e39ea2898c6e11c188e2f3879e4e3d6d1ef: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors
Now please run:
$ tar xvf perf.data.tar.bz2 -C ~/.debug
wherever you need to run 'perf report' on.
[root@intel-s3e36-01 perf]# ./perf --version
perf version 2.6.38.rc6.166.g493f33
