[ANNOUNCE] 4.9.257-rt171

[Luis Claudio R. Goncalves]

Hello RT-list!

I'm pleased to announce the 4.9.257-rt171 stable release.

Note that there was a futex/mutex code collision during the merge of v4.9-257.
Even though I believe that it's fixed correctly, anyone with suspicions about
futex/rtmutex behavior in this release should start looking there.

You can get this release via the git tree at:

  git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git

  branch: v4.9-rt
  Head SHA1: 945132447043a93a231db68172d26f08ff977987

Or to build 4.9.257-rt171 directly, the following patches should be applied:

  https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.9.tar.xz

  https://www.kernel.org/pub/linux/kernel/v4.x/patch-4.9.257.xz

  https://www.kernel.org/pub/linux/kernel/projects/rt/4.9/patch-4.9.257-rt171.patch.xz

Enjoy!
Luis
