> I know, memcpy returns the ptr to @dest like a parrot Maybe I need to change the name to remove the "memcpy" substring to avoid this confusion. How about "mcsafe_copy()"? Perhaps with a "__" prefix to point out it is a building block that will get various wrappers around it?? Dan wants a copy_from_nvdimm() that either completes the copy, or indicates where a machine check occurred. I'm going to want a copy_from_user() that has two fault options (user gave a bad address -> -EFAULT, or the source address had an uncorrected error -> SIGBUS). -Tony -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
