[GIT PULL] afs: Fixes

[David Howells]

Hi Linus,

Can you pull these fixes for the AFS filesystem?  They include:

 (1) Make AFS file locking work again.

 (2) Don't write to a page that's being written out, but wait for it to
     complete.

 (3) Do d_drop() and d_add() in the right places.

 (4) Put keys on error paths.

 (5) Remove some redundant code.

Thanks,
David
