Sharing Header Files between Kernel Modules

Sharing Header Files between Kernel Modules

I am using Morty (2.2).

I have several kernel modules with header files that need to accessed by other kernel modules when building.

Where can I install the header files so:

  1.  they can be found by other kernel modules while compiling
  2.  they will be created during an sstate build

I was able to install the header files in: '${STAGING_KERNEL_DIR}/include/linux/exa' (in work-shared). The other modules were able to find the header files, but that approach breaks the build from sstates.

Doesn't installing to ${D}${includedir} in do_install work? (or pick
your directory in ${D}). Note you need to DEPEND on the recipe
installing the files.
