device_kernel_headers is a built-in heder-only lib that provides device-specific kernel headers. The header path is configured via a new product variable SystemIncludeDirs, which is currently the mirror of TARGET_PROJECT_SYSTEM_INCLUDES in the make world. Note: generic kernel headers (bionic/libc/kernel) have been added to the include path by default. "device_kernel_headers" module is for device-specific kernel headers such as /device/*/*/kernel-headers. Note 2: this is opt-in for Android.bp modules (i.e. header_libs : ["device_kernel_headers"] required.) while it is always provided to Android.mk modules. Bug: 62939405 Test: choosecombo to aosp_sailfish (or any other Pixel/Nexus targets) BOARD_VNDK_VERSION=current m -j gralloc.msm8996 (or any other vendor libs using vendor-specific kernel headers) Change-Id: I81c60abc13942c89fff723d1544b27a81b300db0
