Dear RT folks!
I'm pleased to announce the v5.15-rt17 patch set.
Changes since v5.15-rt16:
- Remove put_cpu_var() in fscache which removal was overseen in the
last release.
- Redo the fs/dcache/start_dir_add() related patch and its
description.
- Drop preempt_disable_rt(), no more users.
Known issues
- netconsole triggers WARN.
- The "Memory controller" (CONFIG_MEMCG) has been disabled.
- Valentin Schneider reported a few splats on ARM64, see
