Hi, [Resend: the patches were accidentally sent to linux-media instead. Apologies.] This patchset is aimed to fix a problem in arch_iommu implementation references. When an actual arch_iommu implementation is not loaded while iommu_get() is being called results to a kernel oops, as well as removing an arch_iommu implementation which is in use. This patchset fixes both issues. The patchset assumes the arch_iommu is uninstalled at module unload time. Is this an acceptable requirement? Serialisation of the access to arch_iommu is done using mutex called arch_iommu_mutex. module_put() doesn't need to have the arch_iommu_mutex since when this gets called there won't be any users on the arch_iommu anyway. Comments are welcome. :-) Cheers, -- Sakari Ailus sakari.ailus@xxxxxxxxxxxxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
