Minimally rewrite the XArray unit tests to use kunit. This integrates nicely with existing kunit tools which produce nicer human-readable output compared to the existing machinery. Running the xarray tests before this change requires an obscure invocation ``` tools/testing/kunit/kunit.py run --arch arm64 --make_options LLVM=1 \ --kconfig_add CONFIG_TEST_XARRAY=y --raw_output=all nothing ``` which on failure produces ``` BUG at check_reserve:513 ... XArray: 6782340 of 6782364 tests passed ``` and exits 0. Running the xarray tests after this change requires a simpler invocation ``` tools/testing/kunit/kunit.py run --arch arm64 --make_options LLVM=1 \ xarray ``` which on failure produces (colors omitted) ``` [09:50:53] ====================== check_reserve ====================== [09:50:53] [FAILED] param-0 [09:50:53] # check_reserve: EXPECTATION FAILED at lib/test_xarray.c:536 [09:50:53] xa_erase(xa, 12345678) != NULL ... [09:50:53] # module: test_xarray [09:50:53] # xarray: pass:26 fail:3 skip:0 total:29 [09:50:53] # Totals: pass:28 fail:3 skip:0 total:31 [09:50:53] ===================== [FAILED] xarray ====================== ``` and exits 1. Use of richer kunit assertions is intentionally omitted to reduce the scope of the change.
