Subject: [Qemu-devel] [PATCH 6/6] file-posix: Remove .bdrv_inactivate/invalidate_cache
Date: Thu,  4 May 2017 18:52:41 +0200	[thread overview]
Message-ID: <1493916761-32319-7-git-send-email-kwolf@redhat.com> (raw)
In-Reply-To: <1493916761-32319-1-git-send-email-kwolf@redhat.com>

Now that the block layer takes care to request a lot less permissions
for inactive nodes, the special-casing in file-posix isn't necessary any
more.
