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.

2006-01-06[BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn()Tejun Heo
add @uptodate argument to end_that_request_last() and @error to rq_end_io_fn(). there's no generic way to pass error code to request completion function, making generic error handling of non-fs request difficult (rq->errors is driver-specific and each driver uses it differently). this patch adds @uptodate to end_that_request_last() and @error to rq_end_io_fn(). for fs requests, this doesn't really matter, so just using the same uptodate argument used in the last call to end_that_request_first() should suffice. imho, this can also help the generic command-carrying request jens is working on.

2006-01-03[MMC] Improve MMC card block size selectionRussell King

2006-01-03[ARM] Remove clk_use()/clk_unuse()Russell King
It seems that clk_use() and clk_unuse() are additional complexity which isn't required anymore. Remove them from the clock framework to avoid the additional confusion which they cause, and update all ARM machine types except for OMAP. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-12-22[MMC] Set correct capacity for 1024-byte block cardsRussell King
We were passing set_capacity() the capacity we calculated in terms of the number of blocks on the card, which happened to be the right units for 512-byte block cards. However, with 1024-byte block cards, we end up setting the capacity to half the number of blocks. Fix this by shifting by the appropriate amount. Thanks to Todd Blumer for pointing this out. Use get_capacity() to report the card capacity, rather than recalculating it from the CSD information. Finally, use our chosen IO block size for the SET_BLOCKLEN command rather than the CSD read block size. Currently these are equivalent, but will not be in the future.

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King
In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.
