Yes SMB can work over QUIC. It would be nice if there was an in-kernel
implementation that cifs.ko could use. Many firewall block port 445
(SMB) despite the newer version of the protocol now having encryption,
signing, etc. Using QUIC (UDP port 443) would allow for more reliable
connectivity to cloud storage like azure.

There are already multiple well-tested C QUIC implementation out there
(Microsoft one for example, has a lot of extra code annotation to allow
for deep static analysis) but I'm not sure how we would go about porting
it to linux.
