Subject: [ANNOUNCE] 3.18.29-rt30


Dear RT Folks,

I'm pleased to announce the 3.18.29-rt30 stable release.

Note, 3.18.29-rt29 was also released that only included the stable
update. But -rt30 is released because the last pull of changes to
3.18-rt included a change that was also reverted in upstream. This
release includes both the stable update and that revert.

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: v3.18-rt
  Head SHA1: 18303cd31e84f06eb780dd58ea213e4a515609fc


Or to build 3.18.29-rt30 directly, the following patches should be applied:

  http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.18.tar.xz

  http://www.kernel.org/pub/linux/kernel/v3.x/patch-3.18.29.xz

  http://www.kernel.org/pub/linux/kernel/projects/rt/3.18/patch-3.18.29-rt30.patch.xz



You can also build from 3.18.29-rt29 by applying the incremental patch:

  http://www.kernel.org/pub/linux/kernel/projects/rt/3.18/incr/patch-3.18.29-rt29-rt30.patch.xz



Enjoy,

-- Steve
