The current sun disklabel code uses a signed int for the sector count.
When partitions larger than 1 TB are used, the cast to a sector_t causes
the partition sizes to be invalid:# cat /proc/paritions | grep sdan
66 112 2146435072 sdan
66 115 9223372036853660736 sdan3
66 120 9223372036853660736 sdan8This patch switches the sector count to an unsigned int to fix this.

Change the partition code in fs/partitions/check.c to initialize a newly
detected partition's policy field with that of the containing block device
(see patch below).My reasoning is that function set_disk_ro() in block/genhd.c modifies the
policy field (read-only indicator) of a disk and all contained partitions.
When a partition is detected after the call to set_disk_ro(), the policy
field of this partition will currently not inherit the disk's policy field.
This behavior poses a problem in cases where a block device can be
'logically de- and reactivated' like e.g. the s390 DASD driver because
partition detection may run after the policy field has been modified.Signed-off-by: Peter Oberparleiter

Sometimes partitions claim to be larger than the reported capacity of a
disk device. This patch makes the kernel warn about those partitions.We still permit these patitions to be used. Quoting Andries Brouwer
:Case 1: The kernel is mistaken about the size of the disk. (There are
commands to clip a disk to a certain capacity, there are jumpers to tell a
disk that it should report a certain capacity etc. Usually this is because
of BIOS bugs. In bad cases the machine will crash in the BIOS and hence fail
to boot if the disk reports full capacity.) In such cases actually accessing
the blocks of the partition may work fine, or may work fine after running an
unclip utility. I wrote "setmax" some years ago precisely for this reason.Case 2: There was a messy partition table (maybe just a rounding error) but
the actual filesystem on the partition is contained in the physical disk.
Now using the filesystem goes without problem.Case 3: Both partition and filesystem extend beyond the end of the disk. In
forensic or debugging situations one often uses a copy of the start of a
disk. Now access beyond the end gives an expected I/O error.Signed-off-by: Mike Miller

Like the SUBSYTEM= key we find in the environment of the uevent, this
creates a generic "subsystem" link in sysfs for every device. Userspace
usually doesn't care at all if its a "class" or a "bus" device. This
provides an unified way to determine the subsytem of a device, regardless
of the way the driver core has created it.Signed-off-by: Kay Sievers

Make sure to clear the driverfs_dev pointer when we do del_gendisk() (on
disk removal), so that other users that may still have a ref to the disk
won't try to use the stale pointer.Also move the KOBJ_REMOVE uevent handler up, so that the uevent still
has access to the driverfs_dev data.This all should hopefully fix the problems with MMC umounts after device
removals that caused commit 56cf6504fc1c0c221b82cebc16a444b684140fb7 and
its reversal (1a2acc9e9214699a99389e323e6686e9e0e2ca67).Original problem reported by Todd Blumer and others.

[BLOCK] delay all uevents until partition table is scanned
Here we delay the annoucement of all block device events until the
disk's partition table is scanned and all partition devices are already
created and sysfs is populated.We have a bunch of old bugs for removable storage handling where we
probe successfully for a filesystem on the raw disk, but at the
same time the kernel recognizes a partition table and creates partition
devices.
Currently there is no sane way to tell if partitions will show up or not
at the time the disk device is announced to userspace. With the delayed
events we can simply skip any probe for a filesystem on the raw disk when
we find already present partitions.Signed-off-by: Kay Sievers

This removes statically assigned platform numbers and reworks the
powerpc platform probe code to use a better mechanism. With this,
board support files can simply declare a new machine type with a
macro, and implement a probe() function that uses the flattened
device-tree to detect if they apply for a given machine.We now have a machine_is() macro that replaces the comparisons of
_machine with the various PLATFORM_* constants. This commit also
changes various drivers to use the new macro instead of looking at
_machine.Signed-off-by: Benjamin Herrenschmidt

DASD allows to open a device as soon as gendisk is registered, which means the
device is a fake device (capacity=0) and we do know nothing about blocksize
and partitions at that point of time. In case the device is opened by
someone, the bdev and inode creation is done with the fake device info and the
following partition detection code is just using the wrong data.To avoid this modify the DASD state machine to make sure that the open is
rejected until the device analysis is either finished or an unformatted device
was detected.Signed-off-by: Horst Hummel

but ACORN_PARTITION disabled. Since ACORN_PARTITION controls
whether we build fs/partitions/acorn.c, this lead to undefined

struct gendisk has these two fields: stamp, stamp_idle. Update to
stamp_idle is always in sync with stamp and they are always the same.
Therefore, it does not add any value in having two fields tracking
same timestamp. Suggest to remove it.Also, we should only update gendisk stats with non-zero value.
Advantage is that we don't have to needlessly calculate memory address,
and then add zero to the content.Signed-off-by: Ken Chen

This change from March 3rd causes the partition parsing code to ignore
partitions which have a signature byte of zero. Turns out that more people
have such partitions than we expected, and their device numbering is coming up
wrong in post-2.6.11 kernels.So revert the change while we think about the problem a bit more.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
