Hi all,

After merging the ext4 tree, today's linux-next build (x86_64
allmodconfig) failed like this:

ERROR: modpost: "ext4fs_dirhash" [fs/ext4/ext4-test.ko] undefined!

Caused by commit

   a4841d91a7f57 (ext4: add Kunit coverage for directory hash computation)

I have used the tree from next-20260528 instead.
