History
Poul-Henning Kamp e1657bbb97 Introduce the VOP_OPENEXTATTR() and VOP_CLOSEEXTATTR() methods. 
Together these two implement a simple transcation style grouping for
modifications of extended attributes on a vnode.

VOP_CLOSEEXTATTR() takes a boolean "commit" argument, which determines
if the aggregate changes are attempted written or not.  A commit will
fail if any of the VOP_SETEXTATTR() calls since the VOP_OPENEXTATTR()
have failed to meet their objective or if the flush to disk fails.

The default operations for these two VOP's is to return EOPNOTSUPP.

This API may still be subject to change.
