xfs: ensure dentry consistency when the orphanage adopts a filerepair-orphanage_2022-10-14
When the orphanage adopts a file, that file becomes a child of the
orphanage. The dentry cache may have entries for the orphanage
directory and the name we've chosen, so (1) make sure we abort if the
dcache has a positive entry because something's not right; and (2)
invalidate and purge negative dentries if the adoption goes through.
