Hey there, fellow code enthusiasts! Welcome back to another episode of the Linux Kernel podcast. I'm your host, and wow, do we have some fascinating fixes to dig into today. You know those days when the codebase feels like a well-oiled machine getting its regular maintenance? That's exactly what we're seeing here -…
So today we had zero merged pull requests in the traditional sense, but don't let that fool you - we've got six substantial commits that tell a really interesting story about how complex systems evolve and get refined over time.
The big story today is all about race conditions and timing issues. You know, those sneaky bugs that only show up when things happen in just the wrong order? Linus has been busy merging some critical fixes that tackle exactly these kinds of problems.
First up, we've got some scheduler extensions fixes that are honestly pretty impressive in their scope. There was this nasty deadlock happening with something called SCX_KICK_WAIT, where multiple CPUs were basically waiting for each other in a circle - imagine four people at a four-way stop all being overly polite…
Then we dive into cgroup fixes, and this is where things get really interesting from a…
