Purpose of kernel development is basically to customize our own recipes kernel by reused existing recipes. This is an initiative of automating manual kernel development test cases. Applying a single patch to the Linux kernel source is one of the manual test cases of kernel development. Objective of this test is as a developer we can make changes of a file in kernel source and able to apply a single patch to the kernel source. ref:https://wiki.yoctoproject.org/wiki/Kernel_Development_Test_Cases (From OE-Core rev: 00a5df641b94ef47eec36e742630db7b659102a4) Signed-off-by: Mazliana <mazliana.mohamad@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
