* Use drive->media and drive->scsi to check if ->dsc_overlap can be set by HDIO_SET_NICE ioctl in generic_ide_ioctl(). * Remove unused ->supports_dsc_overlap field from ide_driver_t.

* Add struct ide_devset, S_* flags, *DEVSET() & ide*_devset_*() macros. * Add 'const struct ide_devset **settings' to ide_driver_t. * Use 'const struct ide_devset **settings' in ide_drive_t instead of 'struct ide_settings_s *settings'. Then convert core code and device drivers to use struct ide_devset and co.: - device settings are no longer allocated dynamically for each device but instead there is an unique struct ide_devset instance per setting - device driver keeps the pointer to the table of pointers to its settings in ide_driver_t.settings - generic settings are kept in ide_generic_setting[] - ide_proc_[un]register_driver(), ide_find_setting_by_name(), ide_{read,write}_setting() and proc_ide_{read,write}_settings() are updated accordingly - ide*_add_settings() are removed * Remove no longer used __ide_add_setting(), ide_add_setting(), __ide_remove_setting() and auto_remove_settings(). * Remove no longer used TYPE_*, SETTING_*, ide_procset_t and ide_settings_t. * ->keep_settings, ->using_dma, ->unmask, ->noflush, ->dsc_overlap, ->nice1, ->addressing, ->wcache and ->nowerr ide_drive_t fields can now be bitfield flags. While at it: * Rename ide_find_setting_by_name() to ide_find_setting(). * Rename write_wcache() to set_wcache(). There should be no functional changes caused by this patch.

Make drive->id an unnamed union so id can be accessed either by using 'u16 *id' or 'struct hd_driveid *driveid'. Then convert all existing drive->id users accordingly (using 'u16 *id' when possible). This is an intermediate step to make ide 'struct hd_driveid'-free.

Right now SCSI and others do their own command timeout handling. Move those bits to the block layer. Instead of having a timer per command, we try to be a bit more clever and simply have one per-queue. This avoids the overhead of having to tear down and setup a timer for each command, so it will result in a lot less timer fiddling.

With the older SG interface, we don't know a user-space address to trasfer data when executing a SCSI command. So we can't pass a user-space address to blk_rq_map_user.

This patch introduces struct rq_map_data to enable bio_copy_use_iov() use reserved pages. Currently, bio_copy_user_iov allocates bounce pages but drivers/scsi/sg.c wants to allocate pages by itself and use them. struct rq_map_data can be used to pass allocated pages to bio_copy_user_iov. The current users of bio_copy_user_iov simply passes NULL (they don't want to use pre-allocated pages).

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.

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.

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.

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: NTejun Heo <tj@kernel.org> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

* Implement disk_devt() and part_devt() and use them to directly access devt instead of computing it from ->major and ->first_minor. Note that all references to ->major and ->first_minor outside of block layer is used to determine devt of the disk (the part0) and as ->major and ->first_minor will continue to represent devt for the disk, converting these users aren't strictly necessary. However, convert them for consistency. * Implement disk_max_parts() to avoid directly deferencing genhd->minors. * Update bdget_disk() such that it doesn't assume consecutive minor space. * Move devt computation from register_disk() to add_disk() and make it the only one (all other usages use the initially determined value). These changes clean up the code and will help disk->part dereference fix and extended block device numbers.
