From 587d82fae258794e33cacc9bf4ba61949184e822 Mon Sep 17 00:00:00 2001 From: Emanuele Giuseppe Esposito Date: Wed, 7 Dec 2022 14:18:24 +0100 Subject: async: Register/unregister aiocontext in graph lock list Add/remove the AioContext in aio_context_list in graph-lock.c when it is created/destroyed. This allows using the graph locking operations from this AioContext. In order to allow linking util/async.c with binaries that don't include the block layer, introduce stubs for (un)register_aiocontext().
