Based on 805b573fad06b845502e76f3db3a0efa7583149d Mon Sep 17 00:00:00 2001
From: Lukas Nykryn <lnykryn@redhat.com>
Date: Wed, 23 Jul 2014 12:49:14 +0200
Subject: [PATCH] sysv: order initscripts which provide $network before
network.target
Due to recent changes where $network "maps" to network-online.target
it is not guaranteed that initscript which provides networking will
be terminated after network.target during shutdown which is against LSB.

From 1f6d36f267186c0e3184bab4c7eca48481c6faab Mon Sep 17 00:00:00 2001
From: Hui Wang <hui.wang@canonical.com>
Date: Wed, 30 Jul 2014 16:09:08 +0800
Subject: [PATCH] keymap: Add microphone mute keymap for Dell Latitude
On the Dell Latitude, the mic mute key event is generated by wmi
driver, the keycode assigned to this hotkey from kernel is
KEY_MICMUTE (248), this keycode is too big for xorg to handle,
in the xorg, the XF86AudioMicMute is assigned to F20.
Please refer to 4e648ea0 of xkeyboard-config.

Subject: [PATCH] keymap: Annotate all micmute workarounds
Add a comment to all assignments to f20 that this actually should be "micmute"
in a future when we aren't limited by X.org's key code limiations any more.

Subject: [PATCH] udevd: add --event-timeout commandline option
Some events take longer than the default 30 seconds. Killing those
events will leave the machine halfway configured.
Add a commandline option '--event-timeout' to handle these cases.

From: Jeff Mahoney <jeffm@suse.com>
Subject: udev: use device mapper target name for btrfs device ready
References: bnc#888215
When udev gets a change event for a block device, it calls the builtin
btrfs helper to scan it for a btrfs file system. If the file system was
mounted using a device mapper node, mount(8) will have looked up the
device mapper table and used the /dev/mapper/<name> node for mount.
If something like partprobe runs, and then causes change events to be
handled, the btrfs ready event is handled using /dev/dm-N instead of
the device mapper named node. Btrfs caches the last name passed to
the scanning ioctl and uses that to report the device name for
things like /proc/mounts.
So, after running partprobe we go from:
/dev/mapper/test-test on /mnt type btrfs (rw,relatime,space_cache)
... to ...
/dev/dm-0 on /mnt type btrfs (rw,relatime,space_cache)
This doesn't apply only to LVM device, but multipath as well.
If the device is a DM device, udev will have already cached the table name
from sysfs and we can use that to pass /dev/mapper/<name> to the builtin
so that the correct name is used.
