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 2021-06-07. Known problem: There is a printk build warning that would be fixed by commit 43a17111c2553 ("printk: wake up klogd in vprintk_emit"), already present in v4.19-rt. I am trying to decide whether it is justifiable to suggest the backport of this commit to 4.14-stable or if I should write a simple rt-only fix. Comments are welcome. To build 4.14.232-rt112-rc1 directly, the following patches should be applied: https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.14.tar.xz https://www.kernel.org/pub/linux/kernel/v4.x/patch-4.14.232.xz https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/patch-4.14.232-rt112-rc1.patch.xz You can also build from 4.14.232-rt111 by applying the incremental patch: https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/incr/patch-4.14.232-rt111-rt112-rc1.patch.xz Enjoy, -- Luis Luis Claudio R.
