Subject: [PATCH V9 08/17] monitor: switch to iothread_unsafe_get_aio_context()
Date: Wed, 24 Jun 2026 15:08:42 +0800	[thread overview]
Message-ID: <20260624070851.13342-9-zhangckid@gmail.com> (raw)
In-Reply-To: <20260624070851.13342-1-zhangckid@gmail.com>

Since previous patches introduced explicit monitor tracking and reference
counting via IOThreadHolder during initialization, standard global calls
to iothread_get_aio_context() are no longer appropriate for raw context
fetches.

Switch the remaining fallback sites in monitor_suspend(), monitor_resume(),
and monitor_init_qmp() to use iothread_unsafe_get_aio_context(). This aligns
with the new safe ref/unref lifecycles introduced for monitor tracking.
