Correct the termination condition of the DVMA pruning loop in iommu_dvma_vallocseg(), which I botched in r1.32. This bug could cause an endless loop when a map was loaded and DVMA was scarce, or that map had a stringent alignment or boundary.
Correct the termination condition of the DVMA pruning loop in
iommu_dvma_vallocseg(), which I botched in r1.32. This bug could
cause an endless loop when a map was loaded and DVMA was scarce,
or that map had a stringent alignment or boundary.
