Hi,
I would like to remove the no-depend keyword from drivers using the
LINUXKPI_C in the kernel. Currently it fails like this:
> sys/ofed/drivers/infiniband/core/mad.c:36:10: fatal error: 'linux/dma-mapping.h' file not found
> #include <linux/dma-mapping.h>
> ^
> 1 error generated.
That's very easy to fix, by simply adding the correct include path to
the C-flags of depend, though then all kernel files will have that
include path added. What is the best way to fix this?
I see ZFS has made a solution and can we extend this scheme?

> SFILES_NOCDDL= ${SFILES:N*/cddl/*}
> CFILES_CDDL= ${CFILES:M*/cddl/*}
> SFILES_CDDL= ${SFILES:M*/cddl/*}
