[PATCH v4 0/2] vhost: support more than 64 memory regions

From: Igor Mammedov
Date: Thu Jul 02 2015 - 09:08:24 EST


changes since v3:
* rebased on top of vhost-next branch
changes since v2:
* drop cache patches for now as suggested
* add max_mem_regions module parameter instead of unconditionally
increasing limit
* drop bsearch patch since it's already queued

References to previous versions:
v2: https://lkml.org/lkml/2015/6/17/276
v1: http://www.spinics.net/lists/kvm/msg117654.html

Series allows to tweak vhost's memory regions count limit.

It fixes VM crashing on memory hotplug due to vhost refusing
accepting more than 64 memory regions with max_mem_regions
set to more than 262 slots in default QEMU configuration.

Igor Mammedov (2):
vhost: extend memory regions allocation to vmalloc
vhost: add max_mem_regions module parameter
