Subject: [PATCH 0/6] AFS fixes


Hi Linus,

Here's a set of fixes for AFS:

 (1) Use struct_size() for kzalloc() size calculation.

 (2) When calling YFS.CreateFile rather than AFS.CreateFile, it is possible
     to create a file with a file lock already held.  The default value
     indicating no lock required is actually -1, not 0.

 (3) Fix an oops in inode/vnode validation if the target inode doesn't have
     a server interest assigned (ie. a server that will notify us of
     changes by third parties).

 (4) Fix refcounting of keys in file locking.

 (5) Fix a race in refcounting asynchronous operations in the event of an
     error during request transmission.  The provision of a dedicated
     function to get an extra ref on a call is split into a separate
     commit.

The patches can be found here:
