Hi all,

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

ERROR: modpost: "__bitmap_or_equal" [lib/test_bitmap.ko] undefined!
ERROR: modpost: "__bitmap_weighted_or" [lib/test_bitmap.ko] undefined!

Caused by commit

  3ceb692949ab9 (bitmap: add test_zero_nbits())

I have used the version from next-20260323 instead.
