Subject: [PATCH 03/21] Drivers: hv: kvp: move poll_channel() to hyperv_vmbus.h
Date: Sat, 11 Apr 2015 18:07:41 -0700	[thread overview]
Message-ID: <1428800879-25816-3-git-send-email-kys@microsoft.com> (raw)
In-Reply-To: <1428800879-25816-1-git-send-email-kys@microsoft.com>

From: Vitaly Kuznetsov <vkuznets@redhat.com>

Move poll_channel() to hyperv_vmbus.h and make it inline and rename it to hv_poll_channel() so it can be reused
in other hv_util modules.
