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-track.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/libsystemd/sd-bus/bus-track.c') diff --git a/src/libsystemd/sd-bus/bus-track.c b/src/libsystemd/sd-bus/bus-track.c index ffa2cf3d75..0a3322a4ee 100644 --- a/src/libsystemd/sd-bus/bus-track.c +++ b/src/libsystemd/sd-bus/bus-track.c @@ -166,7 +166,7 @@ _public_ int sd_bus_track_add_name(sd_bus_track *track, const char *name) { assert_return(track, -EINVAL); assert_return(service_name_is_valid(name), -EINVAL); - r = hashmap_ensure_allocated(&track->names, string_hash_func, string_compare_func); + r = hashmap_ensure_allocated(&track->names, &string_hash_ops); if (r < 0) return r; -- cgit v1.2.3-54-g00ecf
