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
^
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?
# We have "special" -I include paths for zfs/dtrace files in 'depend'.
CFILES_NOCDDL= ${CFILES:N*/cddl/*:N*fs/nfsclient/nfs_clkdtrace*}
SFILES_NOCDDL= ${SFILES:N*/cddl/*}
CFILES_CDDL=${CFILES:M*/cddl/*}
SFILES_CDDL=${SFILES:M*/cddl/*}
Does the following look OK?
