From 49697b065a04d5a5713ba90626dc4259fd007232 Mon Sep 17 00:00:00 2001 From: Ahmad Fatoum Date: Mon, 3 May 2021 13:48:58 +0200 Subject: bbu: add function to directly add handlers into file_list bbu_handlers_iterate() is only used for merging handlers into a file_list. This can be useful for other update mechanisms as well. Export a bbu_append_handlers_to_file_list that does this.
