Hello, Testing of the xarray using the radix tree test suite is currently broken in v6.9-rc1 and beyond. A bisect resulted in your commit failing to build: a60cc288a1a2604bd86d3df129f269887018c3cb is the first bad commit commit a60cc288a1a2604bd86d3df129f269887018c3cb Author: Luis Chamberlain <mcgrof@xxxxxxxxxx> ...
