This patch remove blk_register_filter and blk_unregister_filter in
gendisk, and adds them to sd.c, sr.c. and ide-cd.c
The commit abf5439370 moved cmdfilter
from gendisk to request_queue. It turned out that in some subsystems
multiple gendisks share a single request_queue. So we get:
Using physmap partition information
Creating 3 MTD partitions on "physmap-flash":
0x00000000-0x01c00000 : "User FS"
0x01c00000-0x01c40000 : "booter"

Why?:
There are occasions where userspace would like to access sysfs
attributes for a device but it may not know how sysfs has named the
device or the path. For example what is the sysfs path for
/dev/disk/by-id/ata-ST3160827AS_5MT004CK? With this change a call to
stat(2) returns the major:minor then userspace can see that
/sys/dev/block/8:32 links to /sys/block/sdc.
What are the alternatives?:
1/ Add an ioctl to return the path: Doable, but sysfs is meant to reduce
the need to proliferate ioctl interfaces into the kernel, so this
seems counter productive.
2/ Use udev to create these symlinks: Also doable, but it adds a
udev dependency to utilities that might be running in a limited
environment like an initramfs.
3/ Do a full-tree search of sysfs.

Commit 30f2f0eb4b ("block: do_mounts -
accept root=<non-existant partition>") extended blk_lookup_devt() to be
able to look up partitions that had not yet been registered, but in the
process made the assumption that the '&block_class.devices' list only
contains disk devices and that you can do 'dev_to_disk(dev)' on them.
That isn't actually true. The block_class device list also contains the
partitions we've discovered so far, and you can't just do a
'dev_to_disk()' on those.
So make sure to only work on devices that block/genhd.c has registered
itself, something we can test by checking the 'dev->type' member. This
makes the loop in blk_lookup_devt() match the other such loops in this
file.

This reverts commit 56cf6504fc.
Both Erik Mouw and Andrew Vasquez independently pinpointed this commit
as causing problems, where the slab cache for a driver is never released
(most obviously causing problems when immediately re-loading that
driver, resulting in a "kmem_cache_create: duplicate cache <xyz>"
message, but it can also cause other trouble).
James Bottomley dug into it, and reports:
"OK, here's the scoop. The problem patch adds a get of driverfs_dev in
add_disk(), but doesn't put it again until disk_release() (which occurs
on final put_disk() of the gendisk).
However, in SCSI, the driverfs_dev is the sdev_gendev. That means
there's a reference held on sdev_gendev until final disk put.
Unfortunately, we use the driver model driver_remove to trigger
del_gendisk (which removes the gendisk from visibility and decrements
the refcount), so we've introduced an unbreakable deadlock in the
reference counting with this.
I suggest simply reversing this patch at the moment. If Russell and
Jens can tell me what they're trying to do I'll see if there's another
way to do it."
so hereby the patch gets reverted, waiting for a better fix.

The block layer keeps a reference (driverfs_dev) to the struct
device associated with the block device, and uses it internally
for generating uevents in block_uevent.
Block device uevents include umounting the partition, which can
occur after the backing device has been removed.
Unfortunately, this reference is not counted. This means that
if the struct device is removed from the device tree, the block
layers reference will become stale.
Guard against this by holding a reference to the struct device
in add_disk(), and only drop the reference when we're releasing
the gendisk kobject - in other words when we can be sure that no
further uevents will be generated for this block device.

The kernel's representation of the disk statistics uses the type unsigned
which is 32b on both 32b and 64b platforms. Unfortunately, most system
tools that work with these numbers that are exported in /proc/diskstats
including iostat read these numbers into unsigned longs. This works fine
on 32b platforms and when the number of IO transactions are small on 64b
platforms. However, when the numbers wrap on 64b platforms & you read the
numbers into unsigned longs, and compare the numbers to previous readings,
then you get an unsigned representation of a negative number. This looks
like a very large 64b number & gives you bizarre readouts in iostat:
ilc4: Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util
ilc4: sda 5.50 0.00 143.96 0.00 307496983987862656.00 0.00 153748491993931328.00 0.00 2136028725038430.00 7.94 55.12 5.59 80.42
Though fixing iostat in user space is possible, and a quick survey
indicates that several other similar tools also use unsigned longs when
processing /proc/diskstats. Therefore, it seems like a better approach
would be to extend the length of the disk_stats structure on 64b
architectures to 64b. The following patch does that. It should not affect
the operation on 32b platforms.
