When I studied the code of mm/swap, I found "1 << (PAGE_SHIFT - 9)" appears many times. So I try to clean up it. 1. Replace "1 << (PAGE_SHIFT - 9)" or similar with SECTORS_PER_PAGE 2. Replace "PAGE_SHIFT - 9" with SECTORS_PER_PAGE_SHIFT 3. Replace "9" with SECTOR_SHIFT 4. Replace "512" with SECTOR_SIZE
Naive question - what is happening about 4096-byte sectors? Do we need to forward-plan?
