[GIT PULL] AFS fixes

[David Howells]

Hi Linus,

Could you pull these fixes to the AFS filesystem in the kernel please?

They fix a variety of bugs.  These include some issues fixed for
consistency with other AFS implementations:

 (*) Handle AFS mode bits better.

 (*) Use the client mtime rather than the server mtime in the protocol.

 (*) Handle the server returning more or less data than was requested in a
     FetchData call.

 (*) Distinguish mountpoints from symlinks based on the mode bits rather
     than preemptively reading every symlink to find out what it actually
     represents.

One other notable change for the user is that files are now flushed on
close analogously with other network filesystems.

Thanks,
David
