Linus has released 6.16-rc6 for testing; it includes a fix for a somewhat scary regression that came up over the week.

So I was flailing around blaming everybody and their pet hamster, because for a while it looked like a drm issue and then a netlink problem (it superficially coincided with separate issues with both of those subsystems).

But I did eventually figure out how to trigger it reliably and then it bisected nicely, and a couple of days have passed, and I'm feeling much better about the release again. We're back on track, and despite that little scare, I think we're in good shape.

The kernel's perf events subsystem can produce high-quality profiles, with full function-call chains, of resource usage within the kernel itself. Developers, however, often would like to see profiles of the whole system in one integrated report with, for example, call-stack information that crosses the boundary between the kernel and user space. Support for unwinding user-space call stacks in the perf events subsystem is currently inefficient at best. A long-running effort to provide reliable, user-space call-stack unwinding within the kernel, which will improve that situation considerably, appears to be reaching fruition.
