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@kernel.org>

..

Building in the test suite now fails in linux/tools/testing/radix-tree:

Can you please have a look?
