Add max opt argument to init_iova_domain(), and use it to set the rcachesWrap that in init_iova_domain_defaults() to avoid the mysterious 0?
Also fix up all users to set this value (at 0, meaning use default).
Sure, I can do something like that. I actually did have separate along those lines in v3 before I decided to change it.
Y'know, at this point I'm now starting to seriously wonder whether moving the rcaches into iommu_dma_cookie wouldn't make a whole lot of things simpler... :/
Does that sound like crazy talk to you, or an idea worth entertaining?
