In brief

This batch of mainline changes focuses on reliability: EDAC/igen6 memory error decoding is corrected for several Intel client SoCs, XFS zoned-storage and quota handling gets important fixes, and sched_ext, workqueue, and cgroup see targeted bug fixes. New EDAC support for Intel Starfire SoCs is also added.

Bug fixes

Fix EDAC/igen6 address decoding on Intel client SoCs

The igen6 EDAC driver had several bugs in its address translation logic: the interleave boundary was off by one, hash-mode channel selection XORed the interleave bit twice, non-hash mode used a hardcoded bit position, and Raptor Lake-P used a wrong error-address format. These are corrected so the reported DIMM/channel matches the hardware.

Why it matters: More accurate ECC error reporting on affected Intel client platforms, including Alder Lake, Raptor Lake, and derivatives.

Fix EDAC device polling sysfs handling

The poll_msec sysfs file used a conversion that could silently truncate large values and accepted zero, which would make the polling work spin without delay. It now rejects out-of-range values.

Why it matters: Prevents CPU-spinning and misconfigured polling intervals when adjusting EDAC device polling.

Fix XFS superblock sync deadlock and zoned-write bugs

XFS no longer holds buffer locks across a synchronous transaction commit, avoiding a deadlock during shutdown. Zoned-storage paths also get fixes for open-zone caching races, lost bio device pointers on stacked devices, incorrect iomap flags, and a NULL dereference with merged ioends.

Why it matters: Prevents hangs and potential data corruption on XFS, particularly with zoned block devices and stacked DM devices.

Fix XFS quota bypass via group ID change

A capability check in XFS used the wrong credential set, letting a user evade group quota by changing a file's group ID. The fix uses a new capable_noaudit() helper that checks effective credentials without triggering audit noise.

Why it matters: Closes a quota enforcement bypass and avoids spurious SELinux audit messages.

Fix sched_ext scheduler bugs

sched_ext gets fixes for spurious scheduler aborts during DSQ ownership races, timer re-arming on kernels without BPF timer CPU pinning, lost vtime credit in flatcg cgroup migration, and silent timer failures in example schedulers. A documentation example also uses the correct exit-info field.

Why it matters: More reliable BPF schedulers, especially for cgroup-aware scheduling and older kernels.

Fix workqueue deadlocks and watchdog edge cases

Workqueue fixes address a use-after-free in unbound pool lifetime, a softirq-triggering bug on PREEMPT_RT, lockdep-recursive locking when draining dead BH pools, and watchdog thresholds that could overflow jiffies.

Why it matters: Prevents crashes and hangs in kernel workqueue operations, particularly on real-time kernels.

Fix cgroup kill and cpuset isolation regressions

A race in cgroup.kill handling could SIGKILL children created with clone3(CLONE_INTO_CGROUP) even when the cgroup was not being killed. Cpuset also failed to preserve CPUs isolated at boot when an isolated partition was released.

Why it matters: Avoids unexpected process termination and keeps boot-isolated CPUs isolated.

New support

Add EDAC support for Intel Starfire SoCs

The igen6 EDAC driver now recognizes Intel Starfire, a Panther Lake derivative, reusing Panther Lake's configuration data.

Why it matters: Enables ECC error reporting on Starfire systems.
