I gave it a quick and simple test. Worked as expected. Last page got mapped at 0x1000, leaving first page unmapped. Of course, either with MAP_FIXED or w/out MAP_FIXED but proper hint (like -1) you can still map first page. This isn't to say I was extra creative in testing. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
