Merge tag '9p-for-4.19-2' of git://github.com/martinetd/linux
Pull 9p updates from Dominique Martinet:
"This contains mostly fixes (6 to be backported to stable) and a few
changes, here is the breakdown:
- rework how fids are attributed by replacing some custom tracking in
a list by an idr
- for packet-based transports (virtio/rdma) validate that the packet
length matches what the header says
- a few race condition fixes found by syzkaller
- missing argument check when NULL device is passed in sys_mount
- a few virtio fixes
- some spelling and style fixes"
