Add the following tests for xbitmap:
1) single bit test: single bit set/clear/find;
2) bit range test: set/clear a range of bits and find a 0 or 1 bit in
the range.

Umm. 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.
Thanks for you suggestions. Please have a check the v18 patches:
The original implementation is put in patch 4, and the proposed changes
are separated into patch 5 (we can merge them to patch 4 later if they
look good to you), and the new APIs are in patch 6.
Best,
Wei
