As might be expected, this function will create a debugfs file to represent
a variable of type size_t.
Similarly, there is a helper for variables of type unsigned long:
struct dentry *debugfs_create_ulong(const char *name, umode_t mode,
struct dentry *parent,
unsigned long *value);
Boolean values can be placed in debugfs with:
