Hi Sebastian,
Just a heads up wrt $subject...
I had done the same in my 5.6 tree, but then 5.7 came along, and I had to revisit due to 34c881745549e adding an allocation under that lock with irqs disabled. The same commit that added the lock added this.
local_irq_save(flags); // For safely calling this_cpu_ptr().
Whacking that instead of converting the lock cures 5.6 and 5.7 woes.
