udev 148
====
Bugfixes.

The option "ignore_device" does no longer exist. There is no way to
ignore an event, as libudev events can not be suppressed by rules.
It only prevented RUN keys from being executed, which results in an
inconsistent behavior in current setups.

BUS=, SYSFS{}=, ID= are long deprecated and should be SUBSYSTEM(S)=,
ATTR(S){}=, KERNEL(S)=. It will cause a warning once for every rule
file from now on.

The support for the deprecated IDE devices has been removed from the
default set of rules. Distros who still care about non-libata drivers
need to add the rules to the compat rules file.

The ID_CLASS property on input devices has been replaced by the more
accurate set of flags ID_INPUT_{KEYBOARD,KEY,MOUSE,TOUCHPAD,TABLET,JOYSTICK}.
These are determined by the new "input_id" prober now. Some devices,
such as touchpads, can have several classes. So if you previously had
custom udev rules which e. g. checked for ENV{ID_CLASS}="kbd", you
need to replace this with ENV{ID_INPUT_KEYBOARD}="?*".

I just upgraded to 148 from 147, and the new input_id does not
seem to be liked by either my main system or a vbox vm.
In the virtual machine, I noticed this after upgrading and
reloading the rules:

  top output:
  20958 root      18  -2  6004  564  476 R 99.6  0.1   0:41.19 input_id

  ps output:
  root     20958 99.0  0.0   6004   564 ?        R<   23:43   \
    1:04 /lib/udev/input_id /devices/virtual/input/mice

After rebooting the machine, it hangs for a long time after the
usb hubs are detected by the kernel, and then I get this:

  udevadm settle - timeout of 120 seconds reached, the event queue
  contains:
    /sys/devices/virtual/input/mice (1124)
  
  ... some other extraneous messages ...

  udevd[1145]: worker [1150] unexpectedly returned with status 0x0100
  udevd[1145]: worker [1150] failed while handling '/devices/virtual/input/mice'


Where do I start with debugging this??

I can reproduce this; it seems to get stuck in an endless loop
traversing its parents.

I'll fix it right now, sorry for the mess!

Sorry again. I'm afraid that distros who already ship 148 need to pull
in this patch, or we do a 148.1 release for this.
