Merge branch 'vsock-fix-transport_-h2g-g2h-dgram-local-toctou-issues'
Michal Luczaj says:
====================
vsock: Fix transport_{h2g,g2h,dgram,local} TOCTOU issues
transport_{h2g,g2h,dgram,local} may become NULL on vsock_core_unregister().
Make sure a poorly timed `rmmod transport` won't lead to a NULL/stale
pointer dereference.
Note that these oopses are pretty unlikely to happen in the wild. Splats
were collected after sprinkling kernel with mdelay()s.
