2008-10-09block: allow disk to have extended device numberTejun Heo
Now that disk and partition handlings are mostly unified, it's easy to allow disk to have extended device number. This patch makes add_disk() use extended device number if disk->minors is zero. Both sd and ide-disk are updated to use this. * sd_format_disk_name() is implemented which can generically determine the drive name. This removes disk number restriction stemming from limited device names. * If sd index goes over SD_MAX_DISKS (which can be increased now BTW), sd simply doesn't initialize minors letting block layer choose extended device number. * If CONFIG_DEBUG_EXT_DEVT is set, both sd and ide-disk always set minors to 0 and use extended device numbers.

2008-10-09block: replace @ext_minors with GENHD_FL_EXT_DEVTTejun Heo
With previous changes, it's meaningless to limit the number of partitions. Replace @ext_minors with GENHD_FL_EXT_DEVT such that setting the flag allows the disk to have maximum number of allowed partitions (only limited by the number of entries in parsed_partitions as determined by MAX_PART constant). This kills not-too-pretty alloc_disk_ext[_node]() functions and makes @minors parameter to alloc_disk[_node]() unnecessary. The parameter is left alone to avoid disturbing the users.

2008-10-09block: implement CONFIG_DEBUG_BLOCK_EXT_DEVTTejun Heo
Extended devt introduces non-contiguos device numbers. This patch implements a debug option which forces most devt allocations to be from the extended area and spreads them out. This is enabled by default if DEBUG_KERNEL is set and achieves... 1. Detects code paths in kernel or userland which expect predetermined consecutive device numbers. 2. When something goes wrong, avoid corruption as adding to the minor of earlier partition won't lead to the wrong but valid device.

2008-10-09sd/ide-disk: apply extended minors to sd and ideTejun Heo
Update sd and ide-disk such that they can take advantage of extended minors. ide-disk already has 64 minors per device and currently doesn't use extended minors although after this patch it can be turned on by simply tweaking constants. sd only had 16 minors per device causing problems on certain peculiar configurations. This patch lifts the restriction and enables it to use upto 64 minors. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

Fix it by calling ide_device_get() before kref_get() and ide_device_put() after kref_put() in all affected device drivers. v2: Brown paper bag time. In v1 cd->drive was referenced after dropping last reference on cd object (which could result in OOPS in ide_device_put() as reported/debugged by Mariusz Kozlowski).
