[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v2 6/6] Remove XenDisk
Windows 8/Server 2012 natively support SCSIOP_UNMAP. XenVbd now also
correctly handles the reporting to enable unmap support. As such, the
functionality provided by XenDisk is no longer needed.
Signed-off-by: Tu Dinh <ngoc-tu.dinh@xxxxxxxxxx>
---
@Owen: I've rebased this on top of "[PATCH 2/4 v2] Refactor Features and
DiskInfo" and "[PATCH 3/4 v2] Consolidate macro'ed access to properties",
without the "XenDisk: Report Discard support by issuing an Inquiry"
patch.
