2025-12-08amdkfd: introduce new ioctl AMDKFD_IOC_CREATE_PROCESSZhu Lingshan
This commit implemetns a new ioctl AMDKFD_IOC_CREATE_PROCESS that creates a new secondary kfd_progress on the FD. To keep backward compatibility, userspace programs need to invoke this ioctl explicitly on a FD to create a secondary kfd_process which replacing its primary kfd_process.

2025-12-08workqueue: Process extra works in rescuer on memory pressureLai Jiangshan
Make the rescuer process more work on the last pwq when there are no more to rescue for the whole workqueue to help the regular workers in case it is a temporary memory pressure relief and to reduce relapse.

2025-12-08workqueue: Process rescuer work items one-by-one using a cursorLai Jiangshan
Previously, the rescuer scanned for all matching work items at once and processed them within a single rescuer thread, which could cause one blocking work item to stall all others. Make the rescuer process work items one-by-one instead of slurping all matches in a single pass. Break the rescuer loop after finding and processing the first matching work item, then restart the search to pick up the next. This gives normal worker threads a chance to process other items which gives them the opportunity to be processed instead of waiting on the rescuer's queue and prevents a blocking work item from stalling the rest once memory pressure is relieved. Introduce a dummy cursor work item to avoid potentially O(N^2) rescans of the work list. The marker records the resume position for the next scan, eliminating redundant traversals. Also introduce RESCUER_BATCH to control the maximum number of work items the rescuer processes in each turn, and move on to other PWQs when the limit is reached.

2025-12-08cpuset: Remove unnecessary checks in rebuild_sched_domains_lockedChen Ridong
Commit 406100f3da08 ("cpuset: fix race between hotplug work and later CPU offline") added a check for empty effective_cpus in partitions for cgroup v2. However, this check did not account for remote partitions, which were introduced later. After commit 2125c0034c5d ("cgroup/cpuset: Make cpuset hotplug processing synchronous"), cpuset hotplug handling is now synchronous. This eliminates the race condition with subsequent CPU offline operations that the original check aimed to fix. Instead of extending the check to support remote partitions, this patch removes all the redundant effective_cpus check. Additionally, it adds a check and warning to verify that all generated sched domains consist of active CPUs, preventing partition_sched_domains from being invoked with offline CPUs.
