    perf buildid-list: Show running kernel build id fix · 7375e151
    Michael Petlan authored
    The --kernel option of perf buildid-list tool should show the running
    kernel buildid.  The functionality has been lost during other changes of
    the related code.
    
    The build_id__sprintf() function should return length of the build-id
    string,  but it was the length of the build-id raw data instead. Due to
    that, some return value checking caused that the final string was not
    printed out.
    
    With this patch the build_id__sprintf() returns the correct value, so
    the --kernel option works again.
    
    Before:
    
    	# perf buildid-list --kernel
    	#
    
    After:
    
    	# perf buildid-list --kernel
