Subject: [PATCH 0/2] Fix two bugs in hugetlbfs MAP_PRIVATE page reservation
Date: Thu, 10 Jul 2008 18:30:01 +0100 (IST) [thread overview]
Message-ID: <20080710173001.16433.87538.sendpatchset@skynet.skynet.ie> (raw)
The following two patches fix minor issues with the MAP_PRIVATE-reservation
support for hugetlbfs that showed up during testing. The first patch fixes a
problem whereby a check is made for MAP_SHARED mappings that is intended for
MAP_PRIVATE mappings only. The second fixes a BUG_ON that is triggered due to
an unaligned address.
Both patches are fixes for
hugetlb-reserve-huge-pages-for-reliable-map_private-hugetlbfs-mappings-until-fork.patch.
Credit goes to Adam Litke for spotting the problems during regression testing.
