The no group check fails if there is more than one meticgroup in the

The first parameter of the match_metric() should be the string, while
the substring should be the second parameter.

Multiple threads, such as with "perf top", may race to initialize a
file system path like hugetlbfs. The racy initialization of the path
leads to at least memory leaks. To avoid this initialize each fs for
reading the mount point path with pthread_once.
Mounting the file system may also be racy, so in... | ```diff
