ionmap_test compilation failed because there is no dma_buf.h on any of
include paths. Moreover, it's better to use the dma_buf.h file of
kernel under test and not the currently running one.
To fix this, add new target to the Makefile, installing Kernel headers
for user space and direct compiler to look for dma_buf.h file there.
This is what gpio has:
../../../../usr/include/linux/gpio.h:
make -C ../../../.. headers_install INSTALL_HDR_PATH=$(shell pwd)/../../../../usr/
I'd like to be consistent with other selftests. Shuah, what's
your opinion on the best way to get the headers?
Thanks,
Laura
