+ * sysdeps/generic/ldsodefs.h (struct dl_scope_free_list): Store
+ void * pointers instead of struct link_map **.
+ (_dl_scope_free): Change argument type to void *.
+ * include/link.h (struct link_map): Change type of l_reldeps
+ to struct link_map_reldeps, move l_reldepsact into that
+ struct too.
+ * elf/dl-deps.c: Include atomic.h.
+ (_dl_map_object_deps): Only change l->l_initfini when it is
+ fully populated, use _dl_scope_free for freeing it. Optimize
+ removal of libs from reldeps by using l_reserved flag, when
+ some removal is needed, allocate a new list instead of
+ reallocating and free the old with _dl_scope_free. Adjust
+ for l_reldeps and l_reldepsact changes.
+ * elf/dl-lookup.c (add_dependency): Likewise. Reorganize to allow
+ searching in l_initfini and l_reldeps without holding dl_load_lock.
+ * elf/dl-fini.c (_dl_sort_fini): Adjust for l_reldeps and
+ l_reldepsact changes.
+ * elf/dl-close.c (_dl_close_worker): Likewise.
+ * elf/dl-open.c (_dl_scope_free): Change argument type to void *.
