      afs: Fix incorrect freeing of the ACL passed to the YFS ACL store op · f4c79144
      David Howells authored
      The cleanup for the yfs_store_opaque_acl2_operation calls the wrong
      function to destroy the ACL content buffer.  It's an afs_acl struct, not
      a yfs_acl struct - and the free function for latter may pass invalid
      pointers to kfree().
      
      Fix this by using the afs_acl_put() function.  The yfs_acl_put()
      function is then no longer used and can be removed.

      afs: Fix warning due to unadvanced marshalling pointer · c80afa1d
      David Howells authored
      When using the afs.yfs.acl xattr to change an AuriStor ACL, a warning
      can be generated when the request is marshalled because the buffer
      pointer isn't increased after adding the last element, thereby
      triggering the check at the end if the ACL wasn't empty.  This just
      causes something like the following warning, but doesn't stop the call
      from happening successfully:
      
          kAFS: YFS.StoreOpaqueACL2: Request buffer underflow (36<108)
      
      Fix this simply by increasing the count prior to the check.
