2008-10-09block: don't depend on consecutive minor spaceTejun Heo
* 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. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-10-09block: misc updatesTejun Heo
This patch makes the following misc updates in preparation for disk->part dereference fix and extended block devt support. * implment part_to_disk() * fix comment about gendisk->part indexing * rename get_part() to disk_map_sector() * don't use n which is always zero while printing disk information in diskstats_show() Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-10-09driver-core: use klist for class device list and implement iteratorTejun Heo
Iterating over entries using callback usually isn't too fun especially when the entry being iterated over can't be manipulated freely. This patch converts class->p->class_devices to klist and implements class device iterator so that the users can freely build their own control structure. The users are also free to call back into class code without worrying about locking. class_for_each_device() and class_find_device() are converted to use the new iterators, so their users don't have to worry about locking anymore either. Note: This depends on klist-dont-iterate-over-deleted-entries patch because class_intf->add/remove_dev() depends on proper synchronization with device removal.

2008-10-09virtio_blk: use a wrapper function to access io context information of IO ↵Fernando Luis Vázquez Cao
requests struct request has an ioprio member but it is never updated because currently bios do not hold io context information. The implication of this is that virtio_blk ends up passing useless information to the backend driver. That said, some IO schedulers such as CFQ do store io context information in struct request, but use private members for that, which means that that information cannot be directly accessed in a IO scheduler-independent way. This patch adds a function to obtain the ioprio of a request. We should avoid accessing ioprio directly and use this function instead, so that its users do not have to care about future changes in block layer structures or what the currently active IO controller is. This patch does not introduce any functional changes but paves the way for future clean-ups and enhancements.

2008-10-06atmel-mci: Initialize BLKR before sending data transfer commandHaavard Skinnemoen
The atmel-mci driver sometimes fails data transfers like this: mmcblk0: error -5 transferring data end_request: I/O error, dev mmcblk0, sector 2749769 end_request: I/O error, dev mmcblk0, sector 2749777 It turns out that this might be caused by the BLKR register (which contains the block size and the number of blocks being transfered) being initialized too late. This patch moves the initialization of BLKR so that it contains the correct value before the block transfer command is sent. This error is difficult to reproduce, but if you insert a long delay (mdelay(10) or thereabouts) between the calls to atmci_start_command() and atmci_submit_data(), all transfers seem to fail without this patch, while I haven't seen any failures with this patch.

Check the return value of led_classdev_register and unregister all registered devices, if registering one device fails. Also the dynamic memory handling is totally bogus. You can't allocate multiple chunks via kzalloc() and expect them to be in order later. I wonder how this ever worked.

2008-10-03leds-fsg: change order of initialization and deinitializationSven Wegener
On initialization, we first do the ioremap and then register the led devices. On deinitialization, we do it in reverse order. This prevents someone calling into the brightness_set functions with an invalid latch_address.

2008-10-03dw_dmac: fix copy/paste bug in taskletHaavard Skinnemoen
The tasklet checks RAW.BLOCK twice, and does not check RAW.XFER. This is obviously wrong, and could theoretically cause the driver to hang.
