[ANNOUNCE] udev 150 release

[Kay Sievers]

Here comes a new udev version. Thanks to all who have contributed to
this release.

The tarball can be found here:
 ftp://ftp.kernel.org/pub/linux/utils/kernel/hotplug/

The development repository can be found here:
 http://www.kernel.org/git/?p=linux/hotplug/udev.git;a=summary

The ChangeLog can be found here:
 http://www.kernel.org/git/?p=linux/hotplug/udev.git;a=blob;hb=HEAD;f=ChangeLog


udev 150
====
Bugfixes.

Kernels with SYSFS_DEPRECATED=y are not supported since a while. Many users
depend on the current sysfs layout and the information not available in the
deprecated layout. All remaining support for the deprecated sysfs layout is
removed now.

Wow, 150 releases, who would have thought.  Thanks so much Kay for
keeping this going.

Nice, we should start to work on removing this option in the kernel now
as well.

thanks,

Yeah, it has gone a long way over the last couple of years. :)

Oh, thanks to you for all the support on the kernel side, and when the
"discussions" get hot, we wouldn't be where we are today without your
continuous support.

Yeah, that would be awesome, and make the "subsystem patch", which
cleans up the last weirdness in sysfs, the artificial split between
classes and buses, really really simple. :)

Thanks,
Kay

I would like that.

Anyone remember what udev version that is needed if we remove that
kernel option?  I'll try to dig through the different distros to see if
it is yet safe to remove.

And the subsystem merge would be good to have as well, I see the crap
that various android drivers are doing with sysfs and want to keep that
from propagating into the mainline kernel.  The subsystem stuff should
stop most of that.

thanks,

Back in Slackware 12.0, we shipped 2.6.21.5 with:
  # CONFIG_SYSFS_DEPRECATED is not set
  # CONFIG_PM_SYSFS_DEPRECATED is not set
and udev-111.  Maybe that's helpful  :-)

It is, thanks.  So I'm guessing the release before this needed that
setting?  If so, is it still being supported, and when was it released?

thanks,

Our previous release, 11.0, shipped with 2.4.something as the
stock kernel, but we did ship 2.6.18 as an optional kernel in
/testing.  That one is definitely too old, as it doesn't even
have SYSFS_DEPRECATED in the config:

  $ grep SYSFS config-generic-2.6.18 
  CONFIG_VIDEO_PVRUSB2_SYSFS=y
  CONFIG_RTC_INTF_SYSFS=m
  CONFIG_SYSFS=y

This should narrow down the search to 2.6.19 or 2.6.20 though.

For what it's worth, 12.0 was shipped on 20070630, and 11.0 went 
out on 20061001.

Thanks a lot of this information, it is most helpful.
