Subject: [PATCH v5 0/7] Fifth revision of the performance improvement patch to the VMware balloon driver

This is the fifth revision fo the path to the VMWare balloon driver. The original
was send to linux-kernel@xxxxxxxxxxxxxxx on 4/14/15 10.29 am PST. Please refer to
the original change for an overview.

- Initial implementation
- Address suggestions by Dmitry Totoknov
- Use UINT_MAX as "infitite" rate instead of special casing -1
- Change commit comment for step 6 to better explain what impact ballooning has
on the VM performance.
- Add missing include header <linux/vmalloc.h> in step 3
- Moved to from git/torvalds/linux master to git/gregkh/char-misc char-misc-next
(4816693286d4ff9219b1cc72c2ab9c589448ebcb) and remove already applied steps
1/9 and 2/9. That changes the numbering of the patches. 3/9 is now 1/7, 4/9 is
not 2/7, etc. There were no merge issues during this transition.

Testing done: recompiled, installed, rebooted and make sure ballooning still


Philip P. Moltmann (5):
VMware balloon: Show capabilities of balloon and resulting
capabilities in the debug-fs node.
VMware balloon: Do not limit the amount of frees and allocations in
non-sleep mode.

VMware balloon: Enable notification via VMCI

Xavier Deguillard (2):
VMware balloon: add batching to the vmw_balloon.
VMware balloon: Update balloon target on each lock/unlock.
