You can do what fsysopts for active translators (it looks like the output of
showtrans).

The process id is usually available in the f_fsid field of the statvfs
structure (the Hurd has fsid in stat, too, I think).  There is no guarantee
that it is a PID (the requirement is that it is a system-wide unique
identifier for the filesystem, so that fsid+inode is a system-wide unique
identifier for a file), but in the Hurd the convention is to use the PID
of the active translator (which is unique, and not reused soon, so it is a
nice fit for this purpose).

So if you want to do something like that, show the f_fsid, not the pid.  That
is a POSIX thing.

Thanks,
Marcus
