Subject: [Qemu-devel] [PATCH v5 5/8] block: Remove bdrv_reset_dirty
Date: Tue, 26 May 2015 11:36:20 +0800	[thread overview]
Message-ID: <1432611383-3779-6-git-send-email-famz@redhat.com> (raw)
In-Reply-To: <1432611383-3779-1-git-send-email-famz@redhat.com>

Using this function would always be wrong because a dirty bitmap must
have a specific owner that consumes the dirty bits and calls
bdrv_reset_dirty_bitmap().

Remove the unused function to avoid future misuse.
