Pull AFS fixes from David Howells:
"Here's a set of patches that fix a number of bugs in the in-kernel AFS
client, including:
- Fix directory locking to not use individual page locks for
directory reading/scanning but rather to use a semaphore on the
afs_vnode struct as the directory contents must be read in a single
blob and data from different reads must not be mixed as the entire
contents may be shuffled about between reads.
- Fix address list parsing to handle port specifiers correctly.
- Only give up callback records on a server if we actually talked to
that server (we might not be able to access a server).
- Fix some callback handling bugs, including refcounting,
whole-volume callbacks and when callbacks actually get broken in
response to a CB.CallBack op.
- Fix some server/address rotation bugs, including giving up if we
can't probe a server; giving up if a server says it doesn't have a
volume, but there are more servers to try.
- Fix the decoding of fetched statuses to be OpenAFS compatible.
- Fix the handling of server lookups in Cache Manager ops (such as
CB.InitCallBackState3) to use a UUID if possible and to handle no
server being found.
- Fix a bug in server lookup where not all addresses are compared.
- Fix the non-encryption of calls that prevents some servers from
being accessed (this also requires an AF_RXRPC patch that has
already gone in through the net tree).
There's also a patch that adds tracepoints to log Cache Manager ops
that don't find a matching server, either by UUID or by address"
