Building header files into the kernel
Building header files into the kernel

Kernel developers learn, one way or another, to be careful about memory use; any memory taken by the kernel is not available for use by the actual applications that people keep the computer around to run. So it is unsurprising that eyebrows went up when Joel Fernandes proposed building the source for all of the kernel's headers files into the kernel itself, at a cost of nearly 4MB of unswappable, kernel-space memory. The discussion is ongoing, but it has already highlighted some pain points felt by Android developers in particular.
