[Xen-devel] [PATCH][XM-TEST] Check that block-list is accurate after detach

[Dan Smith <danms@xxxxxxxxxx>]

This patch adds a test that performs a series of block-attach and
block-detach operations and verifies that block-list accurately
represents the current state of a domain's block devices.

Added a test to verify that devices come and go from block-list
as they are block-attach'd and block-detach'd.
