[ Upstream commit cd25e15e57e68a6b18dc9323047fe9c68b99290b ]
Garbage in plain 9P2000's perm bits is allowed through, which causes it to be able to set (among others) the suid bit. This was presumably not the intent since the unix extended bits are handled explicitly and conditionally on .u.

This one hits both 9P2000 and .u as it appears v9fs has never translated the O_TRUNC flag.

9p is a remote network protocol, and it doesn't support asynchronous notifications from the server. Ensure that we don't hand out any leases since we can't guarantee they'll be broken when a file's contents change.

The GPIO library expects the drivers to return -ENOTSUPP in some cases and not using analogue POSIX code. Make the driver to follow this.
