This patch series copies the core of the tapdisk process from blktap2, with updates coming from blktap2.5. Signed-off-by: Thanos Makatos <thanos.makatos@citrix.com>

This patch series introduces the shared ring used by the front-end to pass request descriptors to tapdisk, as well as responses from tapdisk to the front-end. Requests from this ring end up in tapdisk''s standard request queue. When the tapback daemon detects that the front-end tries to connect to the back-end, it spawns a tapdisk and tells it to connect to the shared ring. The shared
