Create a new attribute for virtio-blk devices that will fetch the serial number of the block device. This attribute can be used by udev to create disk/by-id symlinks for devices that don't have a UUID (filesystem) associated with them. ATA_IDENTIFY strings are special in that they can be up to 20 chars long and aren't required to be NULL-terminated. The buffer is also zero-padded meaning that if the serial is 19 chars or less that we get a NULL terminated string. When copying this value into a string buffer, we must be careful to copy u...

Using Rusty's suggestion I've respun the patch removing the special copy function. I've tested this patch in a guest kernel with and without qemu supplying serial numbers for the block devices and it's working as expected. When qemu supplies serial numbers, the correct value is supplied to /sys/block/vdX/serial and can be used by udev for generating disk/by-id paths (without

...t roughly 160,000 per second. The storm continues even after the drive is re-inserted. It stops after reconnecting with "atacontrol attach ata6". Some variations on this theme: 1) If I do the above but do not re-insert the drive and try "atacontrol attach ata6", I get a "ATA_IDENTIFY timeout", and then a kernel panic "Fatal trap 12: page fault while in kernel mode". 2) If I try using the nForce sata3 ports, I always get some kind of kernel panic on attaching a drive and "atacontrol attach ata4". The NVRAID settings in the BIOS don't matter. I don&...
