Subject: [ANNOUNCE] CFP: Real-Time Microconference - Linux Plumbers Conference
 2021

The Real-time microconference focuses on finishing the last lap of getting the
PREEMPT_RT[1] patch set into mainline. Many of these missing pieces, however, 
are not at the core of real-time features (like locking, and scheduling), but 
instead, on other subsystems that compose the kernel, like file systems and 
memory management. Making this Linux subsystems compatible with PREEMPT_RT 
requires finding a solution that is acceptable by subsystem maintainer, without 
having these subsystems suffer from performance or complexity issues.

Suggested Topics:
 - New tools for PREEMPT_RT analysis [2].
 - How do we teach the rest of the kernel developers how not to break
   PREEMPT_RT?
 - Stable maintainers tools discussion & improvements: [3]
 - The usage of PREEMPT_RT on safety-critical systems: what do we need to do?
 - Make NAPI and the kernel-rt working better together [5]
 - Migrate disable and the problems that they cause on rt tasks [6]
 - It is time to discuss the "BKL"-like style of our preempt/bh/irq_disable()
   synchronization functions.
 - How do we close the documentation gap
 - The status of the merge, and how can we resolve the last issues that block
   the merge
 - Invite the developers of the areas where patches are still under discussion 
   to help to find an agreement
 - How can we improve the testing of the -rt, to follow the problems raised as    
   Linus tree advances?
 - What’s next?
