Split superpage allocation #86

Closed pleiadesian closed 3 years ago

fixed #85

pleiadesian commented 3 years ago

I've tested with a simple fallocate program which fallocates 2G and accesses pgoff 512 and 513. According to trace log, super pages are allocated and page fault is only triggered at pgoff 512.
