Linux Kernel: Late-Cycle Locking and Lifecycle Fixes
This is a late release-candidate fix wave dominated by locking and lifecycle bugs — sched_ext, cgroup, fscrypt, fsverity, and kexec handover all landed fixes for races, deadlocks, or regressions ahead of the 7.2 release.

This is the Linux Kernel briefing for August 4th, 2026.
The signal today is timing bugs. Nearly every merge in this batch fixes a race, a deadlock, or a lifecycle edge case surfacing just before release.
Start with sched_ext. Tejun Heo's fix set, pulled in commit be76b51, closes out several sub-scheduler lifecycle problems: a failed enable could tear down a sub-scheduler that was never fully linked, racing the root scheduler's disable path into a use-after-free. Another fix stops non-ext tasks from wrongly receiving…
That connects directly to the cgroup fixes in 35e66f0. A pressure trigger's poll timer could be re-armed mid-teardown and fire after the cgroup was already freed — now tied to the cgroup's actual lifetime. More notably, writing to a pressure file was forking a worker thread while holding the cgroup mutex, which…
Second theme: filesystem security correctness. fsverity's fix in 848acc8 closes a regression that let truncation succeed on files with verity enabled, even on kernels without verity support — a real integrity check regression. fscrypt's fix in 2e718c8 corrects an ownership check in the set-encryption-policy ioctl to…
Standalone but worth noting: commit c8e0d43…
