# Merge: 45aee68e19a5 73f628ec9e6b
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
#     
#     Pull virtio/vhost fixes from Michael Tsirkin:
#     
#      - Fixes in the iommu and balloon devices.
#     
#      - Disable the meta-data optimization for now - I hope we can get it
#        fixed shortly, but there's no point in making users suffer crashes
#        while we are working on that.
