fat: detect media without partition table correctly

2008-04-28T15:58:47+00:00

I received a complaint that some FAT formated medias (e.g.  sd memory cards)
trigger a "unknown partition table" message even though there is no partition
table and they work correctly, while in general (when e.g.  formated with
mkdosfs or even Windows Vista) this message is not shown.

Currently this seems only to happen when the medias get formatted with Windows
XP (and possibly Win 2000).  Then the boot indicator byte contains garbage
(part of text message) and so do the other parts checked by msdos_paritition
which then later triggers this message.

References: novell bug #364365

Most fat formatted media without partition table contains zeros in the boot
indication and the other tested bytes and so falls through the checks in
msdos_partition, leading it to return with 1 (all is fine).

But some (e.g.  WinXP formatted) fat fomated medias don't use boot_ind and so
the check fails and causes a "unkown partition table" warning eventhough there
is none and everything would be fine.

This additional check directly verifies if there is a fat formatted medium
without a partition table.

block: send disk "change" event for rescan_partitions()

2008-04-20T02:10:24+00:00

Userspace likes to get notified that the disk may have changed, when
rescan_partitions() is called after partitioning or media change. It will
make it possible to update the state of the disk with the "change" event,
before the following partition "add" events are handled.

Block: Fix whole_disk attribute bug

2008-02-07T19:31:46+00:00

The "whole_disk" attribute was not properly converted in the block
device conversion earlier, and if the file is read, bad things can
happen.  This patch fixes this, making the attribute an empty one,
preserving the original functionality.

Many thanks to David Miller for finding this, and pointing me in the
proper place within the block code to look.

There is no need for kobject_unregister() anymore, thanks to Kay's
kobject cleanup changes, so replace all instances of it with

Driver core: convert block from raw kobjects to core devices

2008-01-25T04:40:36+00:00

This moves the block devices to /sys/class/block. It will create a
flat list of all block devices, with the disks and partitions in one
directory. For compatibility /sys/block is created and contains symlinks
to the disks.
