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-event/sd-event.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/libsystemd/sd-event') diff --git a/src/libsystemd/sd-event/sd-event.c b/src/libsystemd/sd-event/sd-event.c index 985ff2829b..b56182dda7 100644 --- a/src/libsystemd/sd-event/sd-event.c +++ b/src/libsystemd/sd-event/sd-event.c @@ -1032,7 +1032,7 @@ _public_ int sd_event_add_child( assert_return(e->state != SD_EVENT_FINISHED, -ESTALE); assert_return(!event_pid_changed(e), -ECHILD); - r = hashmap_ensure_allocated(&e->child_sources, trivial_hash_func, trivial_compare_func); + r = hashmap_ensure_allocated(&e->child_sources, NULL); if (r < 0) return r; @@ -1123,7 +1123,7 @@ _public_ int sd_event_add_post( assert_return(e->state != SD_EVENT_FINISHED, -ESTALE); assert_return(!event_pid_changed(e), -ECHILD); - r = set_ensure_allocated(&e->post_sources, trivial_hash_func, trivial_compare_func); + r = set_ensure_allocated(&e->post_sources, NULL); if (r < 0) return r; -- cgit v1.2.3-54-g00ecf
