2008-04-28fat: detect media without partition table correctlyFrank Seidel
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.

Teach LDM about a new field encountered with Windows Vista. This fixes LDM for people using Vista who have disabled drive letter assignment from one or more volumes. Doing this introduces a so far unknown field in the LDM database in the VOL5 VBLK structure which causes the LDM driver to fail to parse the VBLK structure and hence LDM fails to parse the disk altogether. This patch teaches the driver about this field. Thanks got to Ashton Mills <amills@iinet.com.au> for reporting the problem and working with me on getting it fixed. It is now working for him.

2007-07-11sysfs: kill unnecessary attribute->ownerTejun Heo
sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded.

2007-02-11[PATCH] relax check for AIX in msdos partition tableOlaf Hering
The patch to identify AIX disks and ignore them has caused at least one machine to fail to find the root partition on 2.6.19. The patch is: http://lkml.org/lkml/2006/7/31/117 The problem is some disk formatters do not blow away the first 4 bytes of the disk. If the disk we are installing to used to have AIX on it, then the first 4 bytes will still have IBMA in EBCDIC. The install in question was debian etch. Im not sure what the best fix is, perhaps the AIX detection code could check more than the first 4 bytes. The whole partition info for primary partitions is in this block: dd if=/dev/sdb count=$(( 4 * 16 )) bs=1 skip=$(( 0x1be )) All other data do not matter, beside the 0x55aa marker at the end of the first block.

2007-02-10[PARTITION]: Add whole_disk attribute.Fabio Massimo Di Nitto
Some partitioning systems create special partitions that span the entire disk. One example are Sun partitions, and this whole-disk partition exists to tell the firmware the extent of the entire device so it can load the boot block and do other things. Such partitions should not be treated as normal partitions, because all the other partitions overlap this whole-disk one. So we'd see multiple instances of the same UUID etc. which we do not want. udev and friends can thus search for this 'whole_disk' attribute and use it to decide to ignore the partition.

2006-12-07[PATCH] Fix check_partition routinesSuzuki K P
check_partition() stops its probe once it hits an I/O error from the partition checkers. This would prevent the actual partition checker getting a chance to verify the partition. So this patch lets check_partition() continue probing untill it hits a success while recording the I/O error which might have been reported by the checking routines. Also, it does some cleanup of the partition methods for ibm, atari and amiga to return -1 upon hitting an I/O error.

2006-12-07[PATCH] fix rescan_partitions to return errors properlySuzuki Kp
The current rescan_partition implementation ignores the errors that comes from the lower layer. It reports success for unknown partitions as well as I/O error cases while reading the partition information. The unknown partition is not (and will not be) considered as an error in the kernel, since there are legal users of it (e.g, members of a RAID5 MD Device or a new disk which is not partitioned at all ). Changing this behaviour would scare the user about a serious problem with their disk and is not recommended. Thus for both "unknown partitions" to the Linux (eg., DEC VMS,Novell Netware) and the legal users of NULL partition, would still be reported as "SUCCESS". The patch attached here, scares the user about something which he does need to worry about. i.e, returning -EIO on disk I/O errors while reading the partition information.

2006-10-17[PATCH] fs/partitions/check: add sysfs error handlingJeff Garzik
Handle errors thrown in disk_sysfs_symlinks(), and propagate back to caller. The callers and associated functions don't do a real good job of handling kobject errors anyway (add_partition, register_disk, rescan_partitions), so this should do until something better comes along.
