Subject: [PATCH 15/19] treewide: rename qemu_wait_io_event/qemu_wait_io_event_common
Date: Mon,  8 Sep 2025 12:12:37 +0200	[thread overview]
Message-ID: <20250908101241.2110068-16-pbonzini@redhat.com> (raw)
In-Reply-To: <20250908101241.2110068-1-pbonzini@redhat.com>

Do so before extending it to the user-mode emulators, where there is no
such thing as an "I/O thread".
