Merge tag 'afs-next-20180208' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull afs updates from David Howells:
"Four fixes:
- add a missing put
- two fixes to reset the address iteration cursor correctly
- fix setting up the fileserver iteration cursor.
Two cleanups:
- remove some dead code
- rearrange a function to be more logically laid out
And one new feature:
- Support AFS dynamic root.
With this 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)"
* tag 'afs-next-20180208' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs:
