blkid(8) will be replacement for devkit-disks-part-id, so we have to
be able to found entry in partition table for requested partition.
This functionality is enabled by BLKID_PARTS_ENTRY_DETAILS flag
(see blkid_probe_set_partitions_flags() for more details).
This patch also add a new public function blkid_partlist_devno_to_partition().

Fix the ZFS device detection by looking at multiple uberblocks to see
if any are present, rather than looking for the ZFS boot block which
is not always present.
There may be up to 128 uberblocks, but the first 4 are not written to
disk on a newly-formatted filesystem so check several of them at
different offsets within the uberblock array.

It would be nice to minimize dependence between the disk layout and
disk topology. We have to follow disk topology for alignment_offset
and huge (> 1MiB) I/O sizes only. For all others disks we can use 1MiB
grain and 1MiB offset.

This reverts commit dcb54fafb128ab41772ae217afc6a7612e2cc446,
"cal: remove gcc-ism from nl_langinfo() call".
The code:
int wfd = (int)(intptr_t) nl_langinfo(_NL_TIME_WEEK_1STDAY);
does not work on big-endian machines. The original solution based on
union is better.
Note that the "type punning" is not gcc-ism any more, it's allowed
by C99 (6.5.2.3).

* don't print:
The number of cylinders for this disk is set to 12161.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
we really don't care about MS-DOS or extremely old LILO.
* inform users that DOS-compatible mode is bad and deprecated thing
(It's difficult to use 2048 sectors grain or 4KiB sectors or
alignment_offset in DOS mode where all is based on cylinders...)
* don't check for cylinders boundary in non-DOS mode
* inform about sector and I/O sizes

The previous release 2.17 introduces aligned defaults for the first
and last sectors on the partition. Unfortunately, there is endless

* add heuristic to detect that the device does not provide
topology information. We can use topology if:
- alignment_offset is not 0
- or optimal_io_size is not 0
- or minimal_io_size is not power of 2
* default to 1MiB offset for the start of the first partition
if topology is unknown. This (2048 512-byte sectors)
is Windows Vista default.
* use optimal_io_size, minimal_io_size or 1MiB as a grain for
partitions alignment
Note that this all is used when DOS-compatible mode is disabled.

The alignment_offset is compensation for DOS compatible partitioning.
It usually matches with disk geometry (e.g. 63 sectors), but the
offset is also exported from phy.disks to RAIDs there the geometry
don't match with the offset. So.. don't print unnecessary warning.

Currently, the library does not allow to initialize blkid_probe if the
file (or block device) is empty. The empty file is reported as an
error. That's wrong. The empty file should be interpreted as a file
without any FS or PT. It means that
blkid_do_{probe,safeprobe,fullprobe}()
have to return 1 ("nothing").

This new option allows to set SCHED_RESET_ON_FORK flag for FIFO and RR
policies.
Example:
$ chrt --fifo --reset-on-fork 1 /bin/bash
$ schedutils/chrt --pid $$
pid 31579's current scheduling policy: SCHED_FIFO|SCHED_RESET_ON_FORK
pid 31579's current scheduling priority: 1

From 9262c9832134f8a33ac2ea2854dc6d20acc712d1 Mon Sep 17 00:00:00 2001
From: Adrian Knoth <adi@drcomp.erfurt.thur.de>
Date: Tue, 2 Feb 2010 16:57:23 +0100
Subject: [PATCH] Add support for SCHED_RESET_ON_FORK to chrt
SCHED_RESET_ON_FORK has been added in 2.6.31. If a thread has this flag
set, chrt reports "unknown" policy, which is confusing.
The patch adds support for this new flag. It will (can) only be applied
to SCHED_FIFO or SCHED_RR, so there's no need to catch the other
scheduling policies.

The library does not reset the probing result (e.g. LABEL, VERSION)
when the probing function failed (return value != 0). We have to be
absolutely sure that the FS has been properly detected before we set
LABEL or VERSION or so.

Add probing function for the Be File System to libblkid. It sets LABEL,
VERSION and UUID. But UUID is only set if the be:volume_id attribute is
found in the small_data area of the i-node of the root directory.

Rather than each fs util having its own search policy, unify the paths in
configure and allow them to be tweaked by downstream. In the process,
drop the /etc paths as no one has ever really used these.

The libblkid probing is based on devices from /proc/partitions by
default. This file usually does not contain removable devices (e.g.
CDROMs) and this kind of devices are invisible for libblkid.
The blkid_probe_all_removable() function adds removable block devices
to blkid cache. The probing is based on information from the /sys
directory. The devices which were detected by this function won't be
written to blkid.tab cache file.
