Description

A phase to remove the xattrs created during the scan_extents phase. They are small and harmless, but we should at least make it possible to remove them.

Users might sometimes actively choose not to do this, as it will impose O(n_files) write IOs on the data pool, for no functional change other than reclaiming a little bit of space.
