Subject: [PATCHv2 00/10] mm, xen/balloon: memory hotplug improvements
Date: Fri, 24 Jul 2015 12:47:38 +0100 [thread overview]
Message-ID: <1437738468-24110-1-git-send-email-david.vrabel@citrix.com> (raw)
The series improves the use of hotplug memory in the Xen balloon
driver.
- Reliably find a non-conflicting location for the hotplugged memory
(this fixes memory hotplug in a number of cases, particularly in
dom0).
- Use hotplugged memory for alloc_xenballooned_pages() (keeping more
memory available for the domain and reducing fragmentation of the
p2m).
Changes in v2:
- New BP_WAIT state to signal the balloon process to wait for
userspace to online the new memory.
- Preallocate P2M entries in alloc_xenballooned_pages() so they do not
need allocated later (in a context where GFP_KERNEL allocations are
not possible).
