lru_cache.h: fix comments referring to ts_ instead of lc_

2011-10-14T14:47:43Z

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. Signed-off-by: Philipp Reisner Signed-off-by: Lars Ellenberg

drbd: use clear_bit_unlock() where appropriate

2011-10-14T14:47:42Z

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. Signed-off-by: Philipp Reisner Signed-off-by: Lars Ellenberg

lru_cache: use correct type in sizeof for allocation

2011-05-25T15:39:52Z

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: // @@ type T; identifier x; @@ T *x; ... * x = kzalloc(... * sizeof(T*) * ..., ...); // [akpm@linux-foundation.org: use kcalloc()] Signed-off-by: Ilia Mirkin Acked-by: Lars Ellenberg Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
