If we're still at 1+ hours then little bodges like this are nowhere near sufficient and sterner stuff will be needed. Do we actually need the test? My googling turns up zero instances of anyone reporting the "ioremap on RAM pfn" warning.We get them more than we like, mostly from 3rd party vendors, and esp. those that merely port their windows drivers to linux.
Dang. So wrapping the check in CONFIG_DEBUG_VM would be problematic? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/ . Don't email: <a href=mailto:"dont@kvack.org"> email@kvack.org </a>
