Subject: [PATCH 0/3] hugetlb fixlet v3
Date: Tue, 31 Mar 2015 08:50:45 +0000	[thread overview]
Message-ID: <1427791840-11247-1-git-send-email-n-horiguchi@ah.jp.nec.com> (raw)

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.
