Merge branch 'afs' of git://git./linux/kernel/git/dhowells/linux-fs

Pull AFS fixes and cleanups from David Howells:
 "Here are some patches to the AFS filesystem:

  1) Fix problems in the clean-up parts of the cache manager service
     handler.

  2) Split afs_end_call() introduced in (1) and replace some identical
     code elsewhere with a call to the first half of the split function.

  3) Fix an error introduced in the workqueue PREPARE_WORK() elimination
     commits.

  4) Clean up argument passing to functions called from the workqueue as
     there's now an insulating layer between them and the workqueue.
     This is possible from (3)"
