• 0097f0405   lru_cache.h: fix comments referring to ts_ instead of lc_ ... Browse Code »

  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.

• 4738fa169   drbd: use clear_bit_unlock() where appropriate ... Browse Code »

  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.

• a08aa355a   lru_cache: use correct type in sizeof for allocation ... Browse Code »

  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*) * ..., ...);
  //
