Let use see how the review goes. First I'll give it a high level review to make sure we all talk about the same things. Please CC linux-arch@xxxxxxxxxxxxxxx for the next patch round. Integrating LKL (into arch/um/) is something which needs more audience and feedback from Arnd Bergmann, our global arch maintainer. > > > LKL (Linux Kernel Library) is aiming to allow reusing the Linux kernel code > as extensively as possible with minimal effort and reduced maintenance > overhead. > > Examples of how LKL can be used are: creating userspace applications > (running on Linux and other operating systems) that can read or write Linux > filesystems or can use the Linux networking stack, creating kernel drivers > for other operating systems that can read Linux filesystems, bootloaders > support for reading/writing Linux filesystems, etc. > > With LKL, the kernel code is compiled into an object file that can be > directly linked by applications.
