[PATCH] Fix swiotlb pci_map_sg error handling The overflow checking condition in lib/swiotlb.c was wrong. It would first run a NULL pointer through virt_to_phys before testing it. Since pci_map_sg overflow is not that uncommon and causes data corruption (including broken file systems) when not properly detected I think it's better to fix it in 2.6.15. This affects x86-64 and IA64. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
