That makes it really hard to form a clear view of what the code
looks like after both patchsets have been applied. :(

No, I'm talking about the series that ends up undoing that commit
(i.e. the DA_OP_INCOMPLETE flag goes away again) and turns
args->flags into args->attr_filter as the namespace filter for
lookups. THis also turn adds XFS_ATTR_INCOMPLETE into a lookup
filter.
With this separation of ops vs lookup filters, moving the lookup
filter into the xfs_name makes a bit more sense (i.e. the namespace
filter is passed with the attribute name), but as a standalone
movement it creates a bit of an impedence mismatch between the xname
and the use of these flags.
I think the end result will be fine, but it's making it hard for me
to reconcile the changes in the two patchsets...
Cheers,
Dave.
