Nope, its supposed to work with all of them, I'll check and try to fix
it.

Re: perf test vfs_getname failed

2017-10-23 Thread Li Zhijian

Those cases can be passed on fedora-26 with the same kernel(and configuration) 
with rhel7.1
[root@localhost perf]# ./perf test vfs_getname
60: Add vfs_getname probe to get syscall args filenames   : Ok
61: Use vfs_getname probe to get syscall args filenames   : Ok
62: Check open filename arg using perf trace + vfs_getname: Ok

totally, i tested at 3 distro
1. fedora-26: OK
2. ubuntu 16.04: FAIL
3. rhel7.1 beta: FAIL

Does it means that those cases are related to special distro(require special 
middle wares) ?


Thanks
