[PATCH] v9fs-copy-transport-proto.patch

[Latchesar Ionkov <lucho@ionkov.net>]

Signed-off-by: Latchesar Ionkov <lucho@ionkov.net>

Attach copy of the transport prototype to the v9fs session, not the prototype
itself. Otherwise two sessions using the same transport type will overwrite
each other's data.
