on umount put_super is called
void jffs2_put_super (struct super_block *sb)
{
SNIP
	jffs2_free_ino_caches(c);
	jffs2_free_raw_node_refs(c);
	vfree(c->blocks);
SNIP
}
So everything is freed there. Are you looking at the first line of output from 
free (Mem:) ? Have a look at the second line (-/+ buffers/cache). If this is 
worrying you too, then send output of free before mount and after umount.
