I could do some git archeology to see what the fs, mm and block core changes were to stop using bdi congested but a pointer to associated changes (or quick recap) would save me some time.
Also, curious to know how back-pressure should be felt back up the IO stack now? (apologies if these are well worn topics, I haven't been tracking this area of development).
Thanks, Mike
