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.

2006-09-30[PATCH] BLOCK: Make it possible to disable the block layer [try #6]David Howells
Make it possible to disable the block layer. Not all embedded devices require it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require the block layer to be present. This patch does the following: (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev support. (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls an item that uses the block layer. This includes: (*) Block I/O tracing. (*) Disk partition code. (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS. (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the block layer to do scheduling. Some drivers that use SCSI facilities - such as USB storage - end up disabled indirectly from this. (*) Various block-based device drivers, such as IDE and the old CDROM drivers. (*) MTD blockdev handling and FTL. (*) JFFS - which uses set_bdev_super(), something it could avoid doing by taking a leaf out of JFFS2's book. (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is, however, still used in places, and so is still available. (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and parts of linux/fs.h. (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK. (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK. (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK is not enabled. (*) fs/no-block.c is created to hold out-of-line stubs and things that are required when CONFIG_BLOCK is not set: (*) Default blockdev file operations (to give error ENODEV on opening). (*) Makes some /proc changes: (*) /proc/devices does not list any blockdevs. (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK. (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK. (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if given command other than Q_SYNC or if a special device is specified. (*) In init/do_mounts.c, no reference is made to the blockdev routines if CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2. (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return error ENOSYS by way of cond_syscall if so). (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if CONFIG_BLOCK is not set, since they can't then happen.

2006-09-29[PATCH] ignore partition table on disks with AIX labelOlaf Hering
The on-disk data structures from AIX are not known, also the filesystem layout is not known. There is a msdos partition signature at the end of the first block, and the kernel recognizes 3 small (and overlapping) partitions. But they are not usable. Maybe the firmware uses it to find the bootloader for AIX, but AIX boots also if the first block is cleared. This is the content of the partition table: # dd if=/dev/sdb count=$(( 4 * 16 )) bs=1 skip=$(( 0x1be )) | xxd 0000000: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 0000010: 80ff ffff 41ff ffff 1b11 0000 381b 0000 ....A.......8... 0000020: 00ff ffff 41ff ffff 0211 0000 1900 0000 ....A........... 0000030: 80ff ffff 41ff ffff 1b11 0000 381b 0000 ....A.......8... Handle the whole disk as empty disk. This fixes also YaST which compares the output from parted (and formerly fdisk) with /proc/partitions. fdisk recognizes the AIX label since a long time, SuSE has a patch for parted to handle the disk label as unknown. dmesg will look like this: sda: [AIX] unknown partition table Tested on an IBM B50 with AIX V4.3.3.

2006-08-26[DISKLABEL] SUN: Fix signed int usage for sector countJeff Mahoney

2006-07-10[PATCH] partitions: let partitions inherit policy from diskPeter Oberparleiter
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.

2006-06-23[PATCH] make kernel warn about incorrectly sized partitionsMike Miller
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 <Andries.Brouwer@cwi.nl>: 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.

2006-05-12Alternative fix for MMC oops on unmount after removalLinus Torvalds
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).

2006-04-14[PATCH] BLOCK: delay all uevents until partition table is scannedKay Sievers
[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.

2005-11-01[BLOCK] Unify the seperate read/write io stat fields into arraysJens Axboe
Instead of having ->read_sectors and ->write_sectors, combine the two into ->sectors[2] and similar for the other fields. This saves a branch several places in the io path, since we don't have to care for what the actual io direction is. On my x86-64 box, that's 200 bytes less text in just the core (not counting the various drivers). Signed-off-by: Jens Axboe <axboe@suse.de>

A "coldplug + udevstart" can be simple like this: for i in /sys/block/*/*/uevent; do echo 1 > $i; done for i in /sys/class/*/*/uevent; do echo 1 > $i; done for i in /sys/bus/*/devices/*/uevent; do echo 1 > $i; done Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-10-28[patch] remove gendisk->stamp_idle fieldChen, Kenneth W
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 <kenneth.w.chen@intel.com> Signed-off-by: Jens Axboe <axboe@suse.de>
