[ Upstream commit 1f776799628139d0da47e710ad86eb58d987ff66 ]
Out of tree build using
make M=tools/test/nvdimm O=/tmp/build -C /tmp/build
fails with the following error
make: Entering directory '/tmp/build' CC [M] tools/testing/nvdimm/test/nfit.o linux/tools/testing/nvdimm/test/nfit.c:19:10: fatal error: nd-core.h: No such file or directory 19 | #include <nd-core.h> | ^~~~~~~~~~~ compilation terminated.
That is because the kbuild file uses $(src) which points to tools/testing/nvdimm, $(srctree) correctly points to root of the linux source tree.
