For some time we contemplated calling the "struct lru_cache"
a "struct tracked_set", and some comments kept the ts_ prefix.

Fix those to match the member field names.

Some open-coded clear_bit(); smp_mb__after_clear_bit();
should in fact have been smp_mb__before_clear_bit(); clear_bit();

Instead, use clear_bit_unlock() to annotate the intention,
and have it do the right thing.

This has no actual effect, since sizeof(struct hlist_head) ==
sizeof(struct hlist_head *), but it's still the wrong type to use.

The semantic match that finds this problem:
// <smpl>
@@
type T;
identifier x;
@@
T *x;
...
* x = kzalloc(... * sizeof(T*) * ..., ...);
// </smpl>
