Dear RT folks!
I'm pleased to announce the v5.15.2-rt19 patch set.
Changes since v5.15.2-rt18:
- Remove an unused variable in mm/ so that the compiler so there is
neither a warning from the compiler nor a complaint from the bot.
Reported by kernel test robot <lkp@xxxxxxxxx>.
Known issues
- netconsole triggers WARN.
- The "Memory controller" (CONFIG_MEMCG) has been disabled.
- Valentin Schneider reported a few splats on ARM64, see
https://lkml.kernel.org/r/20210810134127.1394269-1-valentin.schneider@xxxxxxx
