Headline changes include completed sched_ext subscheduler support, global per-CPU data for BPF programs, binfmt_misc extensions, the new fchroot() system call, working-set tracking for VMs, a deliberately failing failfs filesystem, ntfs3 alternative data streams, and a long list of SMB server improvements. The merge window for 7.4 opens the next day, though Torvalds notes his schedule will be irregular due to an annual family vacation. Why: For most builders this changes nothing this week: there is no security fix or API break named here that forces action, and distro and cloud-image uptake typically trails a .0 release by weeks. The two items worth a look if you run latency-sensitive or instrumented workloads are sched_ext reaching completion and per-CPU global data for BPF programs; everything else (failfs, fchroot(), ntfs3 streams) is niche or test-only.
