From d5099efc47d4e6ac60816b5381a5f607ab03f06e Mon Sep 17 00:00:00 2001 From: Michal Schmidt Date: Wed, 13 Aug 2014 01:00:18 +0200 Subject: hashmap: introduce hash_ops to make struct Hashmap smaller It is redundant to store 'hash' and 'compare' function pointers in struct Hashmap separately. The functions always comprise a pair. Store a single pointer to struct hash_ops instead. systemd keeps hundreds of hashmaps, so this saves a little bit of memory. --- src/resolve/resolved-dns-cache.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/resolve/resolved-dns-cache.c') diff --git a/src/resolve/resolved-dns-cache.c b/src/resolve/resolved-dns-cache.c index 733ef6348d..33ca4d1a45 100644 --- a/src/resolve/resolved-dns-cache.c +++ b/src/resolve/resolved-dns-cache.c @@ -186,7 +186,7 @@ static int dns_cache_init(DnsCache *c) { if (r < 0) return r; - r = hashmap_ensure_allocated(&c->by_key, dns_resource_key_hash_func, dns_resource_key_compare_func); + r = hashmap_ensure_allocated(&c->by_key, &dns_resource_key_hash_ops); if (r < 0) return r; -- cgit v1.2.3-54-g00ecf
