As I was not there, and I know about as much as anyone
about printk internals, can you please post a recap of
what was discussed, technical and other, about printk
improvements at the kernel-summit?
If there was a pdf/powerpoint, that'd be nice to post too.
Thanks and cheers, Joe

There is a nice summary of the discussion at
https://lwn.net/Articles/737822/
In short, it is the old problem with possible soft-lockups.
There were send many variants of a solution based on offloading
and kthreads. We discussed yet another solution proposed
by Steven.
Best Regards,
Petr
