Subject: [PATCH 3/3] Drivers: hv: vmbus: setup irq after synic is initialized
Date: Tue, 21 Apr 2015 10:17:54 +0200 [thread overview]
Message-ID: <1429604274-12537-4-git-send-email-vkuznets@redhat.com> (raw)
In-Reply-To: <1429604274-12537-1-git-send-email-vkuznets@redhat.com>
vmbus_isr() uses synic pages which are being setup in hv_synic_alloc(), we
need to register this irq handler only after we allocate all the required
pages.
