[Xen-devel] [PATCH 2 of 2] Remove Remus kernel extensions (now distributed with pvops kernel)



# HG changeset patch
# User Brendan Cully <brendan@xxxxxxxxx>
# Date 1283549073 25200
# Node ID 3da9f0de715657ae1d1fa622802564ac845d0be3
# Parent  28b1cd50c43d408c43f89c177b720984168ee196
Remove Remus kernel extensions (now distributed with pvops kernel)

Note that 2.6.18 doesn't have these extensions, so as of this patch
Remus no longer supports 2.6.18 dom0 (2.6.18 is still the preferred
kernel for domU, since it contains the suspend event channel).

- * The operation of the buffer is as follows:
- * When a checkpoint begins, a barrier is inserted into the
- *   network queue by a netlink request (it operates by storing
- *   a pointer to the next packet which arrives and blocking dequeue
- *   when that packet is at the head of the queue).
- * When a checkpoint completes (the backup acknowledges receipt),
- *   currently-queued packets are released.
- * So it supports two operations, barrier and release.
