2025-06-17platform/x86: portwell-ec: Move watchdog device under correct platform hierarchyIvan Hu
Without explicitly setting a parent for the watchdog device, the device is registered with a NULL parent. This causes device_add() (called internally by devm_watchdog_register_device()) to register the device under /sys/devices/virtual, since no parent is provided. The result is: DEVPATH=/devices/virtual/watchdog/watchdog0 To fix this, assign &pdev->dev as the parent of the watchdog device before calling devm_watchdog_register_device(). This ensures the device is associated with the Portwell EC platform device and placed correctly in sysfs as: DEVPATH=/devices/platform/portwell-ec/watchdog/watchdog0 This aligns the device hierarchy with expectations and avoids misplacement under the virtual class.

2025-06-17wifi: mac80211: don't WARN for late channel/color switchJohannes Berg
There's really no value in the WARN stack trace etc., the reason for this happening isn't directly related to the calling function anyway. Also, syzbot has been observing it constantly, and there's no way we can resolve it there - those systems are just slow. Instead print an error message (once) and add a comment about what really causes this message.

2025-06-17aoe: defer rexmit timer downdev work to workqueueJustin Sanders
When aoe's rexmit_timer() notices that an aoe target fails to respond to commands for more than aoe_deadsecs, it calls aoedev_downdev() which cleans the outstanding aoe and block queues. This can involve sleeping, such as in blk_mq_freeze_queue(), which should not occur in irq context. This patch defers that aoedev_downdev() call to the aoe device's workqueue.

2025-06-17aoe: clean device rq_list in aoedev_downdev()Justin Sanders
An aoe device's rq_list contains accepted block requests that are waiting to be transmitted to the aoe target. This queue was added as part of the conversion to blk_mq. However, the queue was not cleaned out when an aoe device is downed which caused blk_mq_freeze_queue() to sleep indefinitely waiting for those requests to complete, causing a hang. This fix cleans out the queue before calling blk_mq_freeze_queue().

2025-06-16drm/etnaviv: Protect the scheduler's pending list with its lockMaíra Canal
Commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when GPU is still active") ensured that active jobs are returned to the pending list when extending the timeout. However, it didn't use the pending list's lock to manipulate the list, which causes a race condition as the scheduler's workqueues are running. Hold the lock while manipulating the scheduler's pending list to prevent a race.

2025-06-16bcachefs: don't return fsck_fix for unfixable node errors in __btree_errBharadwaj Raju
After cd3cdb1ef706 ("Single err message for btree node reads"), all errors caused __btree_err to return -BCH_ERR_fsck_fix no matter what the actual error type was if the recovery pass was scanning for btree nodes. This lead to the code continuing despite things like bad node formats when they earlier would have caused a jump to fsck_err, because btree_err only jumps when the return from __btree_err does not match fsck_fix. Ultimately this lead to undefined behavior by attempting to unpack a key based on an invalid format. Make only errors of type -BCH_ERR_btree_node_read_err_fixable cause __btree_err to return -BCH_ERR_fsck_fix when scanning for btree nodes.

2025-06-16bcachefs: opts.journal_rewindKent Overstreet
Add a mount option for rewinding the journal, bringing the entire filesystem to where it was at a previous point in time. This is for extreme disaster recovery scenarios - it's not intended as an undelete operation. The option takes a journal sequence number; the desired sequence number can be determined with 'bcachefs list_journal' Caveats: - The 'journal_transaction_names' option must have been enabled (it's on by default). The option controls emitting of extra debug info in the journal, so we can see what individual transactions were doing; It also enables journalling of keys being overwritten, which is what we rely on here. - A full fsck run will be automatically triggered since alloc info will be inconsistent. Only leaf node updates to non-alloc btrees are rewound, since rewinding interior btree updates isn't possible or desirable. - We can't do anything about data that was deleted and overwritten. Lots of metadata updates after the point in time we're rewinding to shouldn't cause a problem, since we segragate data and metadata allocations (this is in order to make repair by btree node scan practical on larger filesystems; there's a small 64-bit per device bitmap in the superblock of device ranges with btree nodes, and we try to keep this small). However, having discards enabled will cause problems, since buckets are discarded as soon as they become empty (this is why we don't implement fstrim: we don't need it). Hopefully, this feature will be a one-off thing that's never used again: this was implemented for recovering from the "vfs i_nlink 0 -> subvol deletion" bug, and that bug was unusually disastrous and additional safeguards have since been implemented. But if it does turn out that we need this more in the future, I'll have to implement an option so that empty buckets aren't discarded immediately - lagging by perhaps 1% of device capacity.

AMD's Family 19h-based Models 70h-7fh support 4 unified memory controllers (UMC) per processor die. The amd64_edac driver, however, assumes only 2 UMCs are supported since max_mcs variable for the models has not been explicitly set to 4. The same results in incomplete or incorrect memory information being logged to dmesg by the module during initialization in some instances.

2025-06-16x86,fs/resctrl: Remove inappropriate references to cacheinfo in the resctrl ↵Qinyun Tan
subsystem In the resctrl subsystem's Sub-NUMA Cluster (SNC) mode, the rdt_mon_domain structure representing a NUMA node relies on the cacheinfo interface (rdt_mon_domain::ci) to store L3 cache information (e.g., shared_cpu_map) for monitoring. The L3 cache information of a SNC NUMA node determines which domains are summed for the "top level" L3-scoped events. rdt_mon_domain::ci is initialized using the first online CPU of a NUMA node. When this CPU goes offline, its shared_cpu_map is cleared to contain only the offline CPU itself. Subsequently, attempting to read counters via smp_call_on_cpu(offline_cpu) fails (and error ignored), returning zero values for "top-level events" without any error indication. Replace the cacheinfo references in struct rdt_mon_domain and struct rmid_read with the cacheinfo ID (a unique identifier for the L3 cache). rdt_domain_hdr::cpu_mask contains the online CPUs associated with that domain. When reading "top-level events", select a CPU from rdt_domain_hdr::cpu_mask and utilize its L3 shared_cpu_map to determine valid CPUs for reading RMID counter via the MSR interface. Considering all CPUs associated with the L3 cache improves the chances of picking a housekeeping CPU on which the counter reading work can be queued, avoiding an unnecessary IPI.
