perf test shell probe_vfs_getname: Remove extraneous '=' from probe line number regex
Thomas reported the vfs_getname perf tests failing on s/390, it seems it was just to some extraneous '=' somehow getting into the regexp, remove it, now: root@x1:~# perf test getname 91: Add vfs_getname probe to get syscall args filenames : Ok 93: Use vfs_getname probe to get syscall args filenames : FAILED! 126: Check open filename arg using perf trace + vfs_getname : Ok root@x1:~# Second one remains a mistery, have to take some time to nail it down.
