Subject: [Qemu-devel] [PATCH 0/3] cow conversion to the block API
Date: Fri, 7 May 2010 17:16:58 +0200	[thread overview]
Message-ID: <20100507151658.GA15132@lst.de> (raw)

This series converts the cow image driver to the block API.  This fixes
a failure in qemu-iotests 012, and allows compiling it on window by
removing the dependency on mmap.  The downside is that it's possible
a lot slower for bitmap accesses, at least with the current naive
implementation.  Anyone who cares seriously enough about cow is welcome
to optimize the bitmap access.
