Run 'make headers_check' when building vmlinux
configname: CONFIG_HEADERS_CHECK
Linux Kernel Configuration
└─>Compile-time checks and compiler options
└─>Run 'make headers_check' when building vmlinux
In linux kernel since version 2.6.19 (release Date: 2006-11-29)
This option will extract the user-visible kernel headers whenever
building the kernel, and will run basic sanity checks on them to
ensure that exported files do not attempt to include files which
were not exported, etc.
If you're making modifications to header files which are
relevant for userspace, say 'Y', and check the headers
exported to $(INSTALL_HDR_PATH) (usually 'usr/include' in
your build tree), to make sure they're suitable.
