[PATCH 00/15] AFS fixes

[David Howells]

Here's a set of patches for AFS that fix the following issues:

 (1) Leak of keys on file close.

 (2) Broken error handling in xattr functions.

 (3) Missing locking when updating VL server list.

 (4) 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.

 (5) Callback promise expiry time miscalculation.

 (6) Over invalidation of the callback promise on directories.

 (7) Double locking on callback break waking up file locking waiters.

 (8) Double increment of the vnode callback break counter.

The patches can be found here:
