Because new delayed attribute routines cannot roll
transactions, we carve off the parts of
xfs_attr_rmtval_remove that we can use.  This will help to

Nit: with done initialized here, you can remove the done = 0 further
down in the function. That aside:

Ok, I will pick out that little bit.  Thank you for the reviews!
