Convert all external users of queue limits to using wrapper functions
instead of poking the request queue variables directly.

block: Do away with the notion of hardsect_size

2009-05-22T21:22:54+00:00

Until now we have had a 1:1 mapping between storage device physical
block size and the logical block sized used when addressing the device.
With SATA 4KB drives coming out that will no longer be the case.  The
sector size will be 4KB but the logical block size will remain
512-bytes.  Hence we need to distinguish between the physical block size
and the logical ditto.

This patch renames hardsect_size to logical_block_size.

block: Remove code handling bio_alloc failure with __GFP_WAIT

2009-04-15T10:10:12+00:00

Remove code handling bio_alloc failure with __GFP_WAIT.
GFP_KERNEL implies __GFP_WAIT.

block: don't take lock on changing ra_pages

2008-12-29T07:28:43+00:00

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 Also remove out of date comment for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().

block: make add_partition() return pointer to hd_struct

2008-11-18T14:08:56+00:00

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.

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

2008-10-21T11:49:14+00:00

Now we can switch blkdev_ioctl() block_device/mode

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

2008-10-21T11:49:12+00:00

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.

[PATCH] get rid of blkdev_locked_ioctl()

2008-10-21T11:49:10+00:00

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.
