block: don't take lock on changing ra_pages

2008-12-29T07:28:43Z

There's no need to take queue_lock or kernel_lock when modifying bdi->ra_pages. So remove them. Also remove out of date comment for queue_max_sectors_store(). Signed-off-by: Wu Fengguang Signed-off-by: Jens Axboe

block: make add_partition() return pointer to hd_struct

2008-11-18T14:08:56Z

Make add_partition() return pointer to the new hd_struct on success and ERR_PTR() value on failure. This change will be used to fix md autodetection bug. Signed-off-by: Tejun Heo Cc: Neil Brown Signed-off-by: Jens Axboe

[PATCH] kill the rest of struct file propagation in block ioctls

2008-10-21T11:49:14Z

Now we can switch blkdev_ioctl() block_device/mode Signed-off-by: Al Viro

[PATCH] get rid of struct file use in blkdev_ioctl() BLKBSZSET

2008-10-21T11:49:12Z

We need to do bd_claim() only if file hadn't been opened with O_EXCL and then we have no need to use file itself as owner. Signed-off-by: Al Viro

[PATCH] get rid of blkdev_locked_ioctl()

2008-10-21T11:49:10Z

Most of that stuff doesn't need BKL at all; expand in the (only) caller, merge the switch into one there and leave BKL only around the stuff that might actually need it. Signed-off-by: Al Viro

[PATCH] get rid of blkdev_driver_ioctl()

2008-10-21T11:49:08Z

convert remaining callers to __blkdev_driver_ioctl() Signed-off-by: Al Viro

[PATCH] end of methods switch: remove the old ones

[PATCH] beginning of methods conversion

2008-10-21T11:47:32Z

To keep the size of changesets sane we split the switch by drivers; to keep the damn thing bisectable we do the following: 1) rename the affected methods, add ones with correct prototypes, make (few) callers handle both. That's this changeset. 2) for each driver convert to new methods. *ALL* drivers are converted in this series. 3) kill the old (renamed) methods. Note that it _is_ a flagday; all in-tree drivers are converted and by the end of this series no trace of old methods remain. The only reason why we do that this way is to keep the damn thing bisectable and allow per-driver debugging if anything goes wrong. New methods: open(bdev, mode) release(disk, mode) ioctl(bdev, mode, cmd, arg) /* Called without BKL */ compat_ioctl(bdev, mode, cmd, arg) locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */ Signed-off-by: Al Viro

[PATCH] introduce __blkdev_driver_ioctl()

2008-10-21T11:47:26Z

Analog of blkdev_driver_ioctl() with sane arguments. For now uses fake struct file, by the end of the series it won't and blkdev_driver_ioctl() will become a wrapper around it. Signed-off-by: Al Viro

block: make partition array dynamic

2008-10-09T06:56:08Z

disk->__part used to be statically allocated to the maximum possible number of partitions. This patch makes partition array allocation dynamic. The added overhead is minimal as only real change is one memory dereference changed to RCU one. This saves both a bit of memory and cpu cycles iterating through unoccupied slots and makes increasing partition limit easier. Signed-off-by: Tejun Heo Signed-off-by: Jens Axboe
