No. You've duplicated xbitmap.c into the test framework, so now it can slowly get out of sync with the one in lib/. That's not OK. Put it back the way it was, with the patch I gave you as patch 1/n (relocating xbitmap.c from tools/testing/radix-tree to lib/). Then add your enhancements as patch 2/n. All you should need to change in your 1/n from http://git.infradead.org/users/willy/linux-dax.git/commit/727e401bee5ad7d37e0077291d90cc17475c6392 is a bit of Makefile tooling. Leave the test suite embedded in the file; that way people might remember to update the test suite when adding new functionality.
