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/libsystemd/sd-bus/bus-match.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/libsystemd/sd-bus/bus-match.c') diff --git a/src/libsystemd/sd-bus/bus-match.c b/src/libsystemd/sd-bus/bus-match.c index 88b61a75be..18afe0f12a 100644 --- a/src/libsystemd/sd-bus/bus-match.c +++ b/src/libsystemd/sd-bus/bus-match.c @@ -450,13 +450,13 @@ static int bus_match_add_compare_value( where->child = c; if (t == BUS_MATCH_MESSAGE_TYPE) { - c->compare.children = hashmap_new(trivial_hash_func, trivial_compare_func); + c->compare.children = hashmap_new(NULL); if (!c->compare.children) { r = -ENOMEM; goto fail; } } else if (BUS_MATCH_CAN_HASH(t)) { - c->compare.children = hashmap_new(string_hash_func, string_compare_func); + c->compare.children = hashmap_new(&string_hash_ops); if (!c->compare.children) { r = -ENOMEM; goto fail; -- cgit v1.2.3-54-g00ecf
