There is no list in vnode <=> inode correspondence.

The typecast can go away too.

Whats the point of this change?  list_entry == container_of.
Is list_entry being removed from list.h?

This wont apply as-is to -mm, as the XFS code has moved on.
Please send XFS patches to xfs@oss.sgi.com, Alexey, thanks.

cheers.

It's just a cleanup.  We're not dealing with a list_head here, so don't use
list_head functions on it.

Nope.
