Just wondering why not start with PUD level itself ? Although SUBSECTION_SHIFT
might never reach the PUD level but this will help keep the flags calculations
bit simple and ready for all future changes.
I suppose that it's because these are significantly larger than 2M,
whereas Catalin assumed SUBSECTION_SIZE would not increase?
His comment:
"should cover any changes to SUBSECTION_SHIFT making it *smaller* than
2MB. "
flags = 0;
if (SUBSECTION_SHIFT < PUD_SHIFT)
flags |= NO_PUD_BLOCK_MAPPINGS;
if (SUBSECTION_SHIFT < CONT_PMD_SHIFT)
flags |= NO_PMD_CONT_MAPPINGS;
