H A D | qcow2.h | bd28f835 Mon Sep 13 16:08:52 GMT 2010 Kevin Wolf <kwolf@redhat.com> qcow2: Avoid bounce buffers for AIO read requests
qcow2 used to use bounce buffers for any AIO requests. This does not only imply unnecessary copying, but also unbounded allocations which should be avoided.
This patch removes bounce buffers from the normal AIO read path, and constrains them to a constant size for encrypted images.
