The configuration of the gnulib 'mountlist' module (used by findutils and coreutils, among others) is written in such a way that on OpenBSD it uses the getmntinfo() function https://man.openbsd.org/getmntinfo.3 which, according to this manual page, invokes getfsstat().

It is maintained in gnulib, module 'mountlist'. Bruno
