Subject: [PATCH v2 08/16] hw/xen: do not use aio_set_fd_handler(is_external=true) in xen_xenstore
Date: Wed, 19 Apr 2023 13:28:09 -0400 [thread overview]
Message-ID: <20230419172817.272758-9-stefanha@redhat.com> (raw)
In-Reply-To: <20230419172817.272758-1-stefanha@redhat.com>
There is no need to suspend activity between aio_disable_external() and
aio_enable_external(), which is mainly used for the block layer's drain
operation.
This is part of ongoing work to remove the aio_disable_external() API.
