Subject: [PATCH 0/7] afs: Fixes and dynamic root


Hi Linus,

Here are a set of AFS patches, 4 fixes, 2 cleanups and 1 devel patch.  The
fixes are:

 (1) Add a missing put.

 (2) & (3) Reset the address iteration cursor correctly.

 (4) Fix setting up the fileserver iteration cursor.

The cleanups:

 (5) Remove some dead code.

 (6) Rearrange a function to be more logically laid out.

And the development patch:

 (7) Support AFS dynamic root.

With these patches, one should be able to do, say:

	mkdir /afs
	mount -t afs none /afs -o dyn

to create a dynamic root and then, provided you have keyutils installed, do:

	ls /afs/grand.central.org

and:

	ls /afs/umich.edu

to list the root volumes of both those organisations' AFS cells without
requiring any other setup (the kernel upcall to a program in the keyutils
package to do DNS access as does NFS).

The patches can be found here also:

tagged thusly:

	afs-next-20180208
