Subject: Using QUIC from kernel drivers

We have been trying to experiment with using QUIC for access to
network file systems (Samba, Windows etc. over SMB3.1.1 over QUIC) but
cifs.ko is a kernel driver.

Are there any examples of using QUIC from Linux kernel drivers? Or
suggestions on how to do this (I didn't see any QUIC kernel drivers
yet from a "git grep" of 5.6-rc7).  Presumably worst case scenario is
that the kernel driver could upcall for the authentication phase, and
then presumably there is a better way to avoid upcalls for the rest.

There were some details on how Windows did this at the annual large
Storage Developer Conference (https://youtu.be/xUvfjZXIu9E) but was
wondering if any progress with figuring out how kernel drivers can use
QUIC.
