Pull misc AFS fixes from David Howells:
"This fixes a set of miscellaneous issues in the afs filesystem,
including:
- leak of keys on file close.
- broken error handling in xattr functions.
- missing locking when updating VL server list.
- volume location server DNS lookup whereby preloaded cells may not
ever get a lookup and regular DNS lookups to maintain server lists
consume power unnecessarily.
- incorrect error propagation and handling in the fileserver
iteration code causes operations to sometimes apparently succeed.
- interruption of server record check/update side op during
fileserver iteration causes uninterruptible main operations to fail
unexpectedly.
- callback promise expiry time miscalculation.
- over invalidation of the callback promise on directories.
- double locking on callback break waking up file locking waiters.
- double increment of the vnode callback break counter.
Note that it makes some changes outside of the afs code, including:
- an extra parameter to dns_query() to allow the dns_resolver key
just accessed to be immediately invalidated. AFS is caching the
results itself, so the key can be discarded.
- an interruptible version of wait_var_event().
- an rxrpc function to allow the maximum lifespan to be set on a
call.
- a way for an rxrpc call to be marked as non-interruptible"
