[S390] partitions: fix build error in ibm partition detection code

2010-08-13T08:06:55+00:00

9c867fbe "partitions: fix sometimes unreadable partition strings" coverted
one line within the ibm partition code incorrectly. Fix this to get rid of
a build error.

fs/partitions/ibm.c: In function 'ibm_partition':
[...]
fs/partitions/ibm.c:185: error: too many arguments to function 'strlcat'

partitions: fix sometimes unreadable partition strings

2010-08-11T15:59:20+00:00

Fix this garbage happening quite often:

==>	 sda:
	scsi 3:0:0:0: CD-ROM            TOSHIBA
==>	 sda1 sda2 sda3 sda4 	 sda5 sda6 sda7 >

Make "sda: sda1 ..." lines actually lines.

[S390] dasd: use correct label location for diag fba disks

2010-07-19T07:22:50+00:00

Partition boundary calculation fails for DASD FBA disks under the
following conditions:
- disk is formatted with CMS FORMAT with a blocksize of more than
  512 bytes
- all of the disk is reserved to a single CMS file using CMS RESERVE
- the disk is accessed using the DIAG mode of the DASD driver

Under these circumstances, the partition detection code tries to
read the CMS label block containing partition-relevant information
from logical block offset 1, while it is in fact located at physical
block offset 1.

Fix this problem by using the correct CMS label block location
depending on the device type as determined by the DASD SENSE ID
information.

block: use struct parsed_partitions *state universally in partition check code

2010-05-21T18:01:02+00:00

Make the following changes to partition check code.

* Add ->bdev to struct parsed_partitions.

* Introduce read_part_sector() which is a simple wrapper around
  read_dev_sector() which takes struct parsed_partitions *state
  instead of @bdev.

* For functions which used to take @state and @bdev, drop @bdev.  For
  functions which used to take @bdev, replace it with @state.

* While updating, drop superflous checks on NULL state/bdev in ldm.c.

This cleans up the API a bit and enables better handling of IO errors
during partition check as the generic partition check code now has
much better visibility into what went wrong in the low level code
paths.

block: Do away with the notion of hardsect_size

2009-05-22T21:22:54+00:00

Until now we have had a 1:1 mapping between storage device physical
block size and the logical block sized used when addressing the device.
With SATA 4KB drives coming out that will no longer be the case.  The
sector size will be 4KB but the logical block size will remain
512-bytes.  Hence we need to distinguish between the physical block size
and the logical ditto.

This patch renames hardsect_size to logical_block_size.

[S390] dasd: add large volume support

2009-03-26T14:24:05+00:00

The dasd device driver will now support ECKD devices with more then
65520 cylinders.
In the traditional ECKD adressing scheme each track is addressed
by a 16-bit cylinder and 16-bit head number. The new addressing
scheme makes use of the fact that the actual number of heads is
never larger then 15, so 12 bits of the head number can be redefined
to be part of the cylinder address.

[S390] fixed cdl-format detection.

2007-07-10T09:24:44+00:00

CDL formated DASDs are now detected correctly even if no VOL1 label is
on the disk. This prevents possible loss of data.

[PATCH] Fix check_partition routines

2006-12-07T16:39:30+00:00

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.
