Subject: [PATCH v4 13/34] libxc: Implementation of XEN_XSPLICE_op in libxc
Date: Tue, 15 Mar 2016 13:56:35 -0400 [thread overview]
Message-ID: <1458064616-23101-14-git-send-email-konrad.wilk@oracle.com> (raw)
In-Reply-To: <1458064616-23101-1-git-send-email-konrad.wilk@oracle.com>
The underlaying toolstack code to do the basic
operations when using the XEN_XSPLICE_op syscalls:
- upload the payload,
- get status of an payload,
- list all the payloads,
- apply, check, replace, and revert the payload.

v2: Actually set zero for the _pad entries.
v3: Split status into state and error code.
Add REPLACE action.
v4: Use timeout and utilize pads.
v5: Update per Wei's review.
v6: Update per Wei's review.
v7: Extra space slipped in, remove it
