Re: Part V: Compiling Your Kernel

NO RATINGS
@arkamax: you're really talking about the kernel's emergency page pool (GFP_ATOMIC allocates from there).  There's a #define that proovides a guidline for the size of the emergency page pool.  But, at the moment, I can't recall the define's location :(.  However, it's really bad form to use GFP_ATOMIC allocations indescriminantly.  I'd recommend a detailed analisys of the driver to find where they really need ATOMIC vs. the normal GFP_KERNEL allocations and fix the driver.
