Subject: [Qemu-devel] [PULL 12/48] block/qapi: Pass bdrv_query_blk_stats() s->stats
Date: Tue, 29 Mar 2016 17:08:12 +0200	[thread overview]
Message-ID: <1459264128-12761-13-git-send-email-kwolf@redhat.com> (raw)
In-Reply-To: <1459264128-12761-1-git-send-email-kwolf@redhat.com>

From: Max Reitz <mreitz@redhat.com>

bdrv_query_blk_stats() does not need access to all of BlockStats,
BlockDeviceStats is enough and is what this function is actually
supposed to fill.
