[PATCH RT 00/10] Linux 3.12.54-rt73-rc1

[Steven Rostedt <rostedt@goodmis.org>]

Dear RT Folks,

This is the RT stable review cycle of patch 3.12.54-rt73-rc1.

Please scream at me if I messed something up. Please test the patches too.

Note, I'm bringing this tree up to stable patches in 4.1.7-rt8.
Then I'll be pulling 4.1-rt into stable, as development is now on 4.4-rt.
After that, I'll be pulling the 4.1-rt stable changes into the stable trees.

The -rc release will be uploaded to kernel.org and will be deleted when
the final release is out. This is just a review release (or release candidate).

The pre-releases will not be pushed to the git repository, only the
final release is.

If all goes well, this patch will be converted to the next main release
on 2/29/2016.

Enjoy,

-- Steve
