Yes.

The sysctl's table tree is accessible via sys/ directory of proc filesystem.
Since this function is called by sysctl(2), we don't have a mount point.
On the assumption that proc filesystem is mounted on /proc/ , TOMOYO pretends
as if corresponding sysctl table entry under sys/ directory of proc filesystem
is accessed.
