Date: Thu, 23 Jan 2020 15:39:30 -0500
Message-ID: <20200123203930.646725253@goodmis.org> (raw)

Dear RT Folks,

This is the RT stable review cycle of patch 4.19.94-rt39-rc2.

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 1/24/2020.

Enjoy,

-- Steve
