Upcoming Linux kernel 7.3 is one of the most performance-focused updates in years.Btrfs gets 3x to 5x improvements across logging, fsync, extent buffer tracking, and direct I/O. The default free-space cache also switches from v1 to v2.EXT4 is getting faster as well. Parallel direct I/O writes, multi-block allocator improvements via fallocate(), and IOPS jumping from 1.92M to 2.19M on Gen5 NVMe. The scheduler gets a major overhaul bringing massive improvements to frame pacing, especially on "potato"-class hardware.Memory management sees some improvements, too. zsmalloc contention fixes deliver 1.4x to 1.83x gains, with notable benefits for Raspberry Pi. KSM reverse-mapping lock times drop from over 500ms to under 2ms. That is a 100x to 500x improvement.SMP real-time latency improves sharply too. P99 latency falls from 17ms to 1.5ms, which matters a lot for DPDK and real-time workloads.Intel hybrid CPU users on Alder Lake, Lunar Lake, and Panther Lake get better P-core and E-core load balancing.
I don't careThanks nerds for making my computer faster, I probably won't notice but it's nice to know it's happening I guess.

hopefully getting complete AMD HDMI 2.1 FRL+ALLM+VRR support in 7.4But until then you can enable FRL on 7.2 if you add "amdgpu.dcfeaturemask=0x400" to the kernel cmdline.
