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
