blkid_probe_get_wholedisk_devno() isn''t available in some older versions of libblkid. It was used to work around an old bug in blkid_devno_to_wholedisk(), but that has been fixed since 5cd0823 libblkid: fix blkid_devno_to_wholedisk(), present in util-linux 2.17 and beyond. If we happen to be missing that fix, the worst that happens is that we''d fail to detect that a device is

Add commands to automatically prep devices for pass-through The current method for passing through devices requires users to either modify cryptic Linux boot parameters and reboot, or do a lot of manual reads and writes into sysfs nodes. This set of patches introduces commands to make this easier. It expands on the concept of "assignable" (from the list_assignable_devices command).

Over the weekend, I had to make a technical support call on one of my DVD burners, and at one point the recorded message mentioned I should have my serial number handy. I thought there was a way to read that from at least one piece of software on the system, but I couldn't remember one and man -k on a number of subjects was unrevealing. Can someone enlighten me (us)? Thanks. mhr
