Subject: [PATCH RT 0/6] Linux 5.4.74-rt42-rc1


Dear RT Folks,

This is the RT stable review cycle of patch 5.4.74-rt42-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 11/10/2020.

Enjoy,

-- Steve
