Subject: [Patch] vmbus: Simply hv_get_next_write_location() function
Date: Wed, 24 Jan 2018 14:21:30 +0800	[thread overview]
Message-ID: <1516774890-5134-1-git-send-email-Tianyu.Lan@microsoft.com> (raw)

From: Tianyu Lan <Tianyu.Lan@microsoft.com>

The "next" variable is redundant in hv_get_next_write_location().
This patch is to remove it and return write_index directly.
