		--------------------------------------------------------------

		Dentries are dynamically allocated and deallocated, and
		nr_dentry seems to be 0 all the time. Hence it's safe to
		assume that only nr_unused, age_limit and want_pages are
		used. Nr_unused seems to be exactly what its name says.
		Dentries are dynamically allocated and deallocated.

		nr_dentry shows the total number of dentries allocated (active
		+ unused). nr_unused shows the number of dentries that are not
		actively used, but are saved in the LRU list for future reuse.

		Age_limit is the age in seconds after which dcache entries
		can be reclaimed when memory is short and want_pages is
		nonzero when shrink_dcache_pages() has been called and the
		dcache isn't pruned yet.

		nr_negative shows the number of unused dentries that are also
		negative dentries which do not mapped to actual files.
