Linux Kernel: Late-Cycle Cleanup as 7.2 Nears Release
As the 7.2 release candidate matures, five merge commits from Linus Torvalds pull in targeted fixes across scheduler, RDMA, cgroup, and NFS subsystems, with a clear focus on use-after-free bugs and lifecycle correctness rather than new features.

It's July 14th, 2026, and this is your Linux Kernel briefing.
The dominant story today is memory safety and lifecycle correctness, showing up across three separate subsystems as the 7.2 cycle heads toward stabilization.
Start with sched-ext, which pulled in fourteen commits fixing sub-scheduler lifecycle bugs. Tejun Heo's pull describes two use-after-free bugs and an enable-failure path that could leave a half-initialized sub-scheduler still linked into the system. One fix, commit F7574D3, pins the parent scheduler across a child…
That same use-after-free pattern shows up again in RDMA. Jason Gunthorpe's pull fixes crashes in the irdma driver around memory registration, plus a wrong operation order in SIW that let network packets reach a queue pair before it was fully initialized. There's also a denial-of-service concern: unmatched RMPP…
And NFSD gets its own use-after-free fix, this one triggered by unlocking a filesystem after shutdown, patched by Chuck Lever's team in commit 0F26556.
Second theme: correctness over performance. The cgroup fix from Tejun Heo addresses a divide-by-zero in cpuset handling, triggered when a task's memory policy rebinds during CPU hotplug on a cpuset…
