fat: detect media without partition table correctly

2008-08-06T17:11:01Z

commit 0607fd02587a6b4b086dc746d63123c1f284db68 upstream 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: Fix whole_disk attribute bug

2008-02-07T19:31:46Z

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. Acked-by: David S. Miller Cc: Kay Sievers Signed-off-by: Greg Kroah-Hartman

Kobject: convert fs/* from kobject_unregister() to kobject_put()

2008-01-25T04:40:40Z

There is no need for kobject_unregister() anymore, thanks to Kay's kobject cleanup changes, so replace all instances of it with kobject_put(). Cc: Kay Sievers Signed-off-by: Greg Kroah-Hartman

Driver core: convert block from raw kobjects to core devices

2008-01-25T04:40:36Z

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. /sys/class/block |-- sda -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda |-- sda1 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda1 |-- sda10 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda10 |-- sda5 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda5 |-- sda6 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda6 |-- sda7 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda7 |-- sda8 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda8 |-- sda9 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda9 `-- sr0 -> ../../devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0/block/sr0 /sys/block/ |-- sda -> ../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda `-- sr0 -> ../devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0/block/sr0 Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman

kset: convert block_subsys to use kset_create

2008-01-25T04:40:23Z

Dynamically create the kset instead of declaring it statically. We also rename block_subsys to block_kset to catch all users of this symbol with a build error instead of an easy-to-ignore build warning. Cc: Kay Sievers Signed-off-by: Greg Kroah-Hartman

kobject: get rid of kobject_add_dir

kobject_create_and_add is the same as kobject_add_dir, so drop kobject_add_dir. Cc: Kay Sievers Signed-off-by: Greg Kroah-Hartman
