Despite all controversies, Rust in recent times has gained popularity as the second Linux kernel high-level language. The author once decided to go with the flow. What had started as an attempt to overcome zsmalloc inefficiency for large (16K+) pages became a broader initiative to rewrite parts of the swapping infrastructure in Rust, gaining better safety and reducing the code footprint in one...

Following up on an ELC presentation about the future of 32-bit Linux, this is a discussion session specifically about highmem, which is a feature needed for a small number of 32-bit machines that regularly gets kernel developers upset.
The goal of this session is to find consensus on whether we can resonably drop support for highmem in the next few years, what the best time for that would...

Traditionally the drm subsystem has managed memory for GPU devices it it's own space. Device having large amounts of VRAM and mostly being client focused, meant there wasn't a large amount of attention paid to integrating with cgroup memory management.
However this is changing with more GPUs in servers/HPC scenarios and more shared memory devices without device RAM becoming...

A "classic" Use-After-Free (UAF) can occur when resources tied to hot-pluggable devices are accessed after the device has been removed. For example, an open file descriptor may hold references to such resources; if the device is unplugged, subsequent file operations on that descriptor can trigger an UAF. This talk, a follow-up to a previous presentation[1], explores an approach to this...

PREEMPT_RT was merged but the tree is still around. To further improve PREEMPT_RT in certain scenarios, the local bottom halves were introduced allowing to remove locking elsewhere. Another improvement went into to the futex code to allow process private hash. This change allowed another change to improve the hash handling across NUMA nodes.
