partitions: fix broken uevent_suppress conversion

2009-07-12T20:02:09+00:00

git commit f67f129e "Driver core: implement uevent suppress in kobject"
contains this chunk for fs/partitions/check.c:

 	/* suppress uevent if the disk supresses it */
-	if (!ddev->uevent_suppress)
+	if (!dev_get_uevent_suppress(pdev))
 		kobject_uevent(&pdev->kobj, KOBJ_ADD);

However that should have been

-	if (!ddev->uevent_suppress)
+	if (!dev_get_uevent_suppress(ddev))

partitions: add ->set_capacity block device method

2009-06-07T11:52:52+00:00

* Add ->set_capacity block device method and use it in rescan_partitions()
  to attempt enabling native capacity of the device upon detecting the
  partition which exceeds device capacity.

* Add GENHD_FL_NATIVE_CAPACITY flag to try limit attempts of enabling
  native capacity during partition scan.

Together with the consecutive patch implementing ->set_capacity method in
ide-gd device driver this allows automatic disabling of Host Protected Area
(HPA) if any partitions overlapping HPA are detected.

partitions: warn about the partition exceeding device capacity

2009-06-07T11:52:51+00:00

The current warning message says only about the kernel's action taken
without mentioning the underlying reason behind it.

block: Export I/O topology for block devices and partitions

2009-05-22T21:22:55+00:00

To support devices with physical block sizes bigger than 512 bytes we
need to ensure proper alignment.  This patch adds support for exposing
I/O topology characteristics as devices are stacked.

  logical_block_size is the smallest unit the device can address.

  physical_block_size indicates the smallest I/O the device can write
  without incurring a read-modify-write penalty.

  The io_min parameter is the smallest preferred I/O size reported by
  the device.  In many cases this is the same as the physical block
  size.  However, the io_min parameter can be scaled up when stacking
  (RAID5 chunk size > physical block size).

  The io_opt characteristic indicates the optimal I/O size reported by
  the device.  This is usually the stripe width for arrays.

  The alignment_offset parameter indicates the number of bytes the start
  of the device/partition is offset from the device's natural alignment.
  Partition tools and MD/DM utilities can use this to pad their offsets
  so filesystems start on proper boundaries.

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.

Driver core: implement uevent suppress in kobject

2009-03-24T23:38:26+00:00

This patch implements uevent suppress in kobject and removes it
from struct device, based on the following ideas:

1,Uevent sending should be one attribute of kobject, so suppressing it
in kobject layer is more natural than in device layer. By this way,
we can do it for other objects embedded with kobject.

2,It may save several bytes for each instance of struct device.(On my
omap3(32bit ARM) based box, can save 8bytes per device object)

This patch also introduces dev_set|get_uevent_suppress() helpers to
set and query uevent_suppress attribute in case to help kobject
as private part of struct device in future.

[This version is against the latest driver-core patch set of Greg,please
ignore the last version.]
