Subject: [PATCH for-6.1 2/4] migration: Move populate_vfio_info() into a separate file
Date: Wed, 14 Apr 2021 13:20:02 +0200 [thread overview]
Message-ID: <20210414112004.943383-3-thuth@redhat.com> (raw)
In-Reply-To: <20210414112004.943383-1-thuth@redhat.com>
The CONFIG_VFIO switch only works in target specific code. Since
migration/migration.c is common code, the #ifdef does not have
the intended behavior here. Move the related code to a separate
file now which gets compiled via specific_ss instead.
Fixes: 3710586caa ("qapi: Add VFIO devices migration stats in Migration stats")
Signed-off-by: Thomas Huth <thuth@redhat.com>
