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-packet.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'src/resolve/resolved-dns-packet.c') diff --git a/src/resolve/resolved-dns-packet.c b/src/resolve/resolved-dns-packet.c index 0d276df8c9..7375f77481 100644 --- a/src/resolve/resolved-dns-packet.c +++ b/src/resolve/resolved-dns-packet.c @@ -433,9 +433,7 @@ int dns_packet_append_name(DnsPacket *p, const char *name, goto fail; if (allow_compression) { - r = hashmap_ensure_allocated(&p->names, - dns_name_hash_func, - dns_name_compare_func); + r = hashmap_ensure_allocated(&p->names, &dns_name_hash_ops); if (r < 0) goto fail; -- cgit v1.2.3-54-g00ecf
