[PATCH RT 00/16] Linux 4.19.59-rt24-rc1

[Steven Rostedt <rostedt@goodmis.org>]

Dear RT Folks,

This is the RT stable review cycle of patch 4.19.59-rt24-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 7/23/2019.

Enjoy,

-- Steve
