[PATCH v2 0/7] Pass xattr handler to xattr handler operations

[Andreas Gruenbacher <agruenba@redhat.com>]

This is version two of the xattr cleanups.  The main change in the series
is to pass struct xattr_handler down to the xattr handler operations.  In
addition, a few other small problems in the code are fixed.

What's missing is a fix for ocfs2's listxattr operation: ocfs2 implements
list xattr handler operations which should be but actually are not used
from anywhere.  Mark Fasheh is aware of this.

Thanks for the initial feedback.  Are any more changes needed?

Thanks,
Andreas


Changes from version 1:

 * The xattr handler is passed to xattr handler operations as the first
   instead of the last argument.

 * The patches are split per filesystem.

 * The 9p patch introduces an xattr_full_name() helper.  (That helper
   currently isn't used anywhere else.)
