Arnaldo Carvalho de Melo 21316ac680 perf tests shell lib: Use a wildcard to remove the vfs_getname probe ... In some situations the vfs_getname is being added both as requested and with a _1 suffix (inlines?): probe:vfs_getname_1 (on getname_flags:63@acme/git/linux/fs/namei.c with pathname) This ends up making the cleanup to miss that one, as it removes just 'probe:vfs_getname', which makes the second test to use this probe point to fail, since it finds that leftover from the first test, use a wildcard to remove both.
