Subject: [PATCH v5 09/21] hw/xen: do not use aio_set_fd_handler(is_external=true) in xen_xenstore
Date: Thu, 4 May 2023 15:53:15 -0400 [thread overview]
Message-ID: <20230504195327.695107-10-stefanha@redhat.com> (raw)
In-Reply-To: <20230504195327.695107-1-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.
