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: afs: Support the AFS dynamic root afs: Rearrange afs_select_fileserver() a little afs: Remove unused code afs: Fix server list handling afs: Need to clear responded flag in addr cursor afs: Fix missing cursor clearance afs: Add missing afs_put_cell()
