Cover letter [PATCH RT 00/36] Linux 3.12.38-rt53-rc1
Dear RT Folks,
This is the RT stable review cycle of patch 3.12.38-rt53-rc1.
Please scream at me if I messed something up. Please test the patches too.
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 3/16/2015.
Enjoy,
-- Steve
