[Ocfs2-test-devel] [PATCH 1/4] Ocfs2-test: Add kfeature.m4 for ocfs2 to define macro OCFS2_CHECK_KERNEL.

[Sunil Mushran]

This is userspace. So rename it accordingly. As in, drop the K in KAPI.
Also OCFS2_CHECK_KERNEL can become OCFS2_CHECK_HEADERS.
Similarly. You could use /usr/include as the default top dir.

Also, merge patches 2,3,4 into one.
