2007-02-10[PARTITION]: Add whole_disk attribute.Fabio Massimo Di Nitto
Some partitioning systems create special partitions that span the entire disk. One example are Sun partitions, and this whole-disk partition exists to tell the firmware the extent of the entire device so it can load the boot block and do other things. Such partitions should not be treated as normal partitions, because all the other partitions overlap this whole-disk one. So we'd see multiple instances of the same UUID etc. which we do not want. udev and friends can thus search for this 'whole_disk' attribute and use it to decide to ignore the partition.

2006-10-03[PATCH] dm: export blkdev_driver_ioctlAlasdair G Kergon
Export blkdev_driver_ioctl for device-mapper. If we get as far as the device-mapper ioctl handler, we know the ioctl is not a standard block layer BLK* one, so we don't need to check for them a second time and can call blkdev_driver_ioctl() directly.

2006-07-14[PATCH] lockdep: annotate the BLKPG_DEL_PARTITION ioctlArjan van de Ven
The delete partition IOCTL takes the bd_mutex for both the disk and the partition; these have an obvious hierarchical relationship and this patch annotates this relationship for lockdep.

2006-01-08[PATCH] Add block_device_operations.getgeo block device methodChristoph Hellwig
HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.
