[PATCH 0/3] hugetlb fixlet v3

[Naoya Horiguchi]

This is the update of "active page flag for hugetlb" patch [*1].

The main change is patch 2/3, which fixes the race condition where concurrent
call of isolate_huge_page() causes kernel panic.

Patch 1/3 just mentions and "fixes" a potential problem, no behavioral change.
Patch 3/3 is a cleanup, reduces lines of code.
