"Skipped" looks more natural here, with the reason for it skipping being shown
only with -v.
Ingo made some comments about 'perf test' output recently, have you read that?

You mean all these warnings:
[root@zoo ~]# perf test "parse event"
5: parse events tests : Warning: [sunrpc:xprt_lookup_rqst] function __builtin_constant_p not defined
Warning: [sunrpc:xprt_transmit] function __builtin_constant_p not defined
Warning: [sunrpc:xprt_complete_rqst] function __builtin_constant_p not defined
<SNIP>
Warning: [xen:xen_mmu_set_pud] function sizeof not defined
Warning: [xen:xen_mmu_set_pgd] function sizeof not defined
Warning: [xen:xen_mmu_ptep_modify_prot_start] function sizeof not defined
Warning: [xen:xen_mmu_ptep_modify_prot_commit] function sizeof not defined
Ok
[root@zoo ~]#
i.e. making those warnings appear only under 'perf test -v'? Cool!
