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/shared/cgroup-util.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/shared/cgroup-util.c') diff --git a/src/shared/cgroup-util.c b/src/shared/cgroup-util.c index 00eac64236..da8e885226 100644 --- a/src/shared/cgroup-util.c +++ b/src/shared/cgroup-util.c @@ -161,7 +161,7 @@ int cg_kill(const char *controller, const char *path, int sig, bool sigcont, boo * tasks list, to properly handle forking processes */ if (!s) { - s = allocated_set = set_new(trivial_hash_func, trivial_compare_func); + s = allocated_set = set_new(NULL); if (!s) return -ENOMEM; } @@ -239,7 +239,7 @@ int cg_kill_recursive(const char *controller, const char *path, int sig, bool si assert(sig >= 0); if (!s) { - s = allocated_set = set_new(trivial_hash_func, trivial_compare_func); + s = allocated_set = set_new(NULL); if (!s) return -ENOMEM; } @@ -290,7 +290,7 @@ int cg_migrate(const char *cfrom, const char *pfrom, const char *cto, const char assert(cto); assert(pto); - s = set_new(trivial_hash_func, trivial_compare_func); + s = set_new(NULL); if (!s) return -ENOMEM; -- cgit v1.2.3-54-g00ecf
