2025-07-20mm: convert FPB_IGNORE_* into FPB_RESPECT_*David Hildenbrand7-25/+18
Patch series "mm: folio_pte_batch() improvements", v2. Ever since we added folio_pte_batch() for fork() + munmap() purposes, a lot more users appeared (and more are being proposed), and more functionality was added. Most of the users only need basic functionality, and could benefit from a non-inlined version. So let's clean up folio_pte_batch() and split it into a basic folio_pte_batch() (no flags) and a more advanced folio_pte_batch_ext(). Using either variant will now look much cleaner. This series will likely conflict with some changes in some (old+new) folio_pte_batch() users, but conflicts should be trivial to resolve. This patch (of 4): Respecting these PTE bits is the exception, so let's invert the meaning. With this change, most callers don't have to pass any flags. This is a preparation for splitting folio_pte_batch() into a non-inlined variant that doesn't consume any flags. Long-term, we want folio_pte_batch() to probably ignore most common PTE bits (e.g., write/dirty/young/soft-dirty) that are not relevant for most page table walkers: uffd-wp and protnone might be bits to consider in the future. Only walkers that care about them can opt-in to respect them. No functional change intended.

2025-07-20mm/migrate: remove the -EEXIST conversion for move_pages()Wei Yang1-7/+0
The -EEXIST conversion is introduced in commit 65462462ffb2 ("mm/gup: follow_pfn_pte(): -EEXIST cleanup"), since follow_page() may call follow_pfn_pte() which may return -EEXIST. But after commit 7dff875c9436 ("mm/migrate: convert add_page_for_migration() from follow_page() to folio_walk"), it use folio_walk instead. This limit the error code and won't return -EEXIST. Remove the error code conversion here.

2025-07-20mm: fault in complete folios instead of individual pages for tmpfsBaolin Wang1-2/+2
After commit acd7ccb284b8 ("mm: shmem: add large folio support for tmpfs"), tmpfs can also support large folio allocation (not just PMD-sized large folios). However, when accessing tmpfs via mmap(), although tmpfs supports large folios, we still establish mappings at the base page granularity, which is unreasonable. We can map multiple consecutive pages of tmpfs folios at once according to the size of the large folio. On one hand, this can reduce the overhead of page faults; on the other hand, it can leverage hardware architecture optimizations to reduce TLB misses, such as contiguous PTEs on the ARM architecture. Moreover, tmpfs mount will use the 'huge=' option to control large folio allocation explicitly. So it can be understood that the process's RSS statistics might increase, and I think this will not cause any obvious effects for users. Performance test: I created a 1G tmpfs file, populated with 64K large folios, and write-accessed it sequentially via mmap(). I observed a significant performance improvement: Before the patch: real 0m0.158s user 0m0.008s sys 0m0.150s After the patch: real 0m0.021s user 0m0.004s sys 0m0.017s Link: https://lkml.kernel.org/r/440940e78aeb7430c5cc8b6d2088ae98265b9809.1751599072.git.baolin.wang@linux.alibaba.com Fixes: acd7ccb284b8 ("mm: shmem: add large folio support for tmpfs") Signed-off-by: Baolin Wang <baolin.wang@linux.alibaba.com> Acked-by: David Hildenbrand <david@redhat.com> Acked-by: Zi Yan <ziy@nvidia.com> Reviewed-by: Vishal Moola (Oracle) <vishal.moola@gmail.com> Reviewed-by: Barry Song <baohua@kernel.org> Reviewed-by: Lorenzo Stoakes <lorenzo.stoakes@oracle.com> Cc: Baolin Wang <baolin.wang@linux.alibaba.com> Cc: Dev Jain <dev.jain@arm.com> Cc: Hugh Dickins <hughd@google.com> Cc: Liam Howlett <liam.howlett@oracle.com> Cc: Mariano Pache <npache@redhat.com> Cc: Michal Hocko <mhocko@suse.com> Cc: Mike Rapoport <rppt@kernel.org> Cc: Ryan Roberts <ryan.roberts@arm.com> Cc: Suren Baghdasaryan <surenb@google.com> Cc: Vlastimil Babka <vbabka@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

Replace `ListLinksSelfPtr::LIST_LINKS_SELF_PTR_OFFSET` with `unsafe fn raw_get_self_ptr` which returns a pointer to the field rather than requiring the caller to do pointer arithmetic. Implement `HasListLinks::raw_get_list_links` in `impl_has_list_links!`, narrowing the interface of `HasListLinks` and replacing pointer arithmetic with `container_of!`. Modify `impl_list_item` to also invoke `impl_has_list_links!` or `impl_has_list_links_self_ptr!`. This is necessary to allow `impl_list_item` to see more of the tokens used by `impl_has_list_links{,_self_ptr}!`. A similar API change was discussed on the hrtimer series[1].

2025-07-19tracing: Add down_write(trace_event_sem) when adding trace eventSteven Rostedt1-0/+5
When a module is loaded, it adds trace events defined by the module. It may also need to modify the modules trace printk formats to replace enum names with their values. If two modules are loaded at the same time, the adding of the event to the ftrace_events list can corrupt the walking of the list in the code that is modifying the printk format strings and crash the kernel. The addition of the event should take the trace_event_sem for write while it adds the new event. Also add a lockdep_assert_held() on that semaphore in __trace_add_event_dirs() as it iterates the list.

2025-07-19wifi: ath12k: Fix TX status reporting to mac80211 when offload is enabledNithyanantham Paramasivam1-4/+60
Currently, the ath12k driver supports only the native Wi-Fi frame format. In this mode, the ieee80211_tx_status() function works correctly to report transmission status to mac80211, as it retrieves station information using sta_info_get_by_addrs(). However, this method is not applicable for Ethernet-converted packets, since sta_info_get_by_addrs() cannot extract station information from such formats. Retrieve station information using ath12k_peer_find_by_id() to support all frame formats, including native Wi-Fi, raw, and Ethernet. Report transmission status using ieee80211_tx_status_ext(), and include rate information as part of the datapath TX status report.

2025-07-19cgroup: Add compatibility option for content of /proc/cgroupsMichal Koutný2-2/+20
/proc/cgroups lists only v1 controllers by default, however, this is only enforced since the commit af000ce85293b ("cgroup: Do not report unavailable v1 controllers in /proc/cgroups") and there is software in the wild that uses content of /proc/cgroups to decide on availability of v2 (sic) controllers. Add a boottime param that can bring back the previous behavior for setups where the check in the software cannot be changed and it causes e.g. unintended OOMs. Also, this patch takes out cgrp_v1_visible from cgroup1_subsys_absent() guard since it's only important to check which hierarchy (v1 vs v2) the subsys is attached to. This has no effect on the printed message but the code is cleaner since cgrp_v1_visible is really about mounted hierarchies, not the content of /proc/cgroups.

2025-07-19wifi: ath12k: Fix the handling of TX packets in Ethernet modeNithyanantham Paramasivam2-7/+32
Currently, in the transmit (TX) direction, EAPOL, QoS NULL, and multicast frames are sent in native Wi-Fi (802.11) format. However, when the virtual interface is configured in Ethernet mode, transmission fails for packets enqueued in native Wi-fi format. To address this issue, the firmware should be instructed to treat these packets as RAW type packets, ensuring proper handling even when the interface operates in Ethernet mode.

2025-07-19gpio: sysfs: Fix an end of loop test in gpiod_unexport()Dan Carpenter1-3/+6
The test for "if (!desc_data)" does not work correctly because the list iterator in a list_for_each_entry() loop is always non-NULL. If we don't exit via a break, then it points to invalid memory. Instead, use a tmp variable for the list iterator and only set the "desc_data" when we have found a match.
