Right. Index healer threads do a traversal (readdir) of the entries inside .glusterfs/indices/xattrop and attempt heal for each entry.
These threads run  (i) in the while loop, (ii) when a brick process comes back up, (iii)when we explicitly run 'gluster vol heal <volname>'


afr_shd_full_healer() is run only when we run 'gluster vol heal <volname> full`, doing a full brick traversal (readdirp) from the root and attempting heal for each entry.
