Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
Pull vhost infrastructure updates from Michael S. Tsirkin:
"This reworks vhost core dropping unnecessary RCU uses in favor of VQ
mutexes which are used on fast path anyway. This fixes worst-case
latency for users which change the memory mappings a lot. Memory
allocation for vhost-net now supports fallback on vmalloc (same as for
vhost-scsi) this makes it possible to create the device on systems
where memory is very fragmented, with slightly lower performance"
* tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost:
vhost: move memory pointer to VQs
vhost: move acked_features to VQs
vhost: replace rcu with mutex
vhost-net: extend device allocation to vmalloc
