Subject: [GIT PULL] virtio,vhost,vdpa: features, fixes, cleanups
The following changes since commit 830b3c68c1fb1e9176028d02ef86f3cf76aa2476:
Linux 6.1 (2022-12-11 14:15:18 -0800)
are available in the Git repository at:
https://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git tags/for_linus

virtio_blk: mark all zone fields LE (2022-12-22 14:32:36 -0500)
Note: merging this upstream results in a conflict
between commit:
de4eda9de2d9 ("use less confusing names for iov_iter direction initializers")
from Linus' tree and commit:
("virtio/vsock: replace virtio_vsock_pkt with sk_buff")
from this tree.
This resolution below fixes it up, due to Stephen Rothwell
