I'd find a helper script useful in situations where I don't know the error code immediatelly and have to convert it from a hexa value first. Eg. when RAX contains an error code after a BUG_ON: RAX: 00000000ffffffe4 this translates to -28 == -ENOSPC. -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
