Subject: [PATCH 00/24] AFS development
Hi Al,
Here's a set of development patches for AFS if you could pull it for the
upcoming merge window. Its main features are:
(1) Provide wrapper functions for accessing iov iterators, renumber the
iterator types to be more amenable to switching on and provide a new read
discard iterator type (ITER_DISCARD).
(2) Use iov iterators more directly in AFS unmarshalling routines.
(3) Support for retrieving DNS information where the VL server address list
is partitioned by server.
(4) Implement VL server rotation and improve both this and FS server
rotation.
(5) Add support for the YFS variant of the AFS server.
(6) When first attempting to use a server or a list of servers, plumb all the
addresses simultaneously to try and determine the best route.
The patches are tagged here:
git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git
afs-next-20181020
and can also be found on the following branch:
http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/log/?h=afs-next
