Linux Weekly News (LWN.net): Kernel prepatch 7.3-rc7
The 7.3-rc7 kernel prepatch is out for testing.
Executive Summary
The 7.3-rc7 kernel prepatch is out for testing. According to Linus: " As always, I would have preferred to see a smaller rc, but it's not like anything in here looks like a reason to delay the final release. So that's still set for next weekend unless something new comes up. " One notable change that slipped into the mainline this week is the deprecation of the ext4 data=journal mode; it will be removed entirely at the beginning of 2028.
Linux Kernel Subsystems & Performance Audit
From an operating systems and systems programming perspective: - **Upstream Cohesion:** Merging patches upstream prevents fragmented fork debt and guarantees binary compatibility. - **Attack Surface Reduction:** Stripping obsolete legacy subsystems strengthens real-world operational security. - **Resource Determinism:** Enhancements to scheduling and memory management minimize jitter in high-throughput workloads.
Impact on the Open Ecosystem
Ensures kernel infrastructure remains auditable, stable under heavy load, and compliant with modern reproducibility standards.
