[linux-cifs-client] multisession CIFS mounts

[Jeff Layton]

I've been working off and on for the last month or so to try and get
multisession cifs mounts working. I have a design, and have some
progress toward that end but it's not complete yet. I'm still hoping to
get a prototype working by the time SambaXP rolls around.

The more I work on it though, it's really turning out to be a major
mess to bolt this onto the existing CIFS codebase. CIFS was just not
put together with this sort of thing in mind and I have serious doubts
as to whether this is something we can push into the upstream codebase.

I plan to keep working on it, and may even get something working, but
wanted to give you a heads up since I know you have some interest in
getting this working for customers.

I think this sort of thing needs to be designed into the core of the
filesystem. In fact, I think we ought to shoot for making the SMB2
filesystem in linux to support multisession mounts. Doing anything else
is going to just lead to an inferior user experience and lead to more
confusion. Unfortunately, that basically means tossing what there does
exist of smb2fs out the window since much of its core design is taken
from CIFS.
