</div>This is not the right way to do this, you should not include Linux<br>
kernel headers directly that have not been voluntarily exported.<br>
<br>
The kernel exports some header files for use by user-programs from its<br>
include/uapi/ directory. Those kernel headers are staged by the<br>
toolchain build process in staging_dir/toolchain-*/usr/include/linux.<br>
<br>
mempool.h does not appear to be in the headers exported for uapi, so I<br>
am not sure this is referring to the same mempool.h header file, it<br>
could be either some external library, or some internal header that<br>
does not get properly included.<br>
