As reported by Adam Litke and Jon Tollefson one of the libhugetlbfs regression tests triggers a negative overall reservation count. When this occurs where there is no dynamic pool enabled tests will fail.
Following this email are two patches to fix this issue: hugetlb reservations: move region tracking earlier -- simply moves the region tracking code earlier so we do not have to supply prototypes, and hugetlb reservations: fix hugetlb MAP_PRIVATE reservations across vma splits -- which moves us to tracking the consumed reservation so that we can correctly calculate the remaining reservations at vma close time. This stack is against the top of v2.6.25-rc6-mm3, should this solution prove acceptable it would probabally need porting below Nicks multiple hugepage size patches and those updated; if so I would be happy to do that too. Jon could you have a test on this and see if it works out for you. -apw -- To unsubscribe from this list: send the line "unsubscribe kernel-testers" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
