Hi, this is trivial fix for memset null pointer:
diff --git a/drbd/lru_cache.c b/drbd/lru_cache.c
index a3171b6..37ab276 100644
--- a/drbd/lru_cache.c
+++ b/drbd/lru_cache.c
@@ -57,8 +57,8 @@ struct lru_cache *lc_alloc(const char *name, unsigned int e_count,
bytes *= e_count;
bytes += sizeof(struct lru_cache);
lc = vmalloc(bytes);
- memset(lc, 0, bytes);
if (lc) {
+ memset(lc, 0, bytes);
INIT_LIST_HEAD(&lc->in_use);
INIT_LIST_HEAD(&lc->lru);
INIT_LIST_HEAD(&lc->free);
