2024-11-03mm: multi-gen LRU: use {ptep,pmdp}_clear_young_notify()Yu Zhao
When the MM_WALK capability is enabled, memory that is mostly accessed by a VM appears younger than it really is, therefore this memory will be less likely to be evicted. Therefore, the presence of a running VM can significantly increase swap-outs for non-VM memory, regressing the performance for the rest of the system. Fix this regression by always calling {ptep,pmdp}_clear_young_notify() whenever we clear the young bits on PMDs/PTEs.

2024-11-03mm: multi-gen LRU: remove MM_LEAF_OLD and MM_NONLEAF_TOTAL statsYu Zhao
Patch series "mm: multi-gen LRU: Have secondary MMUs participate in MM_WALK". Today, the MM_WALK capability causes MGLRU to clear the young bit from PMDs and PTEs during the page table walk before eviction, but MGLRU does not call the clear_young() MMU notifier in this case. By not calling this notifier, the MM walk takes less time/CPU, but it causes pages that are accessed mostly through KVM / secondary MMUs to appear younger than they should be. We do call the clear_young() notifier today, but only when attempting to evict the page, so we end up clearing young/accessed information less frequently for secondary MMUs than for mm PTEs, and therefore they appear younger and are less likely to be evicted. Therefore, memory that is *not* being accessed mostly by KVM will be evicted *more* frequently, worsening performance. ChromeOS observed a tab-open latency regression when enabling MGLRU with a setup that involved running a VM: Tab-open latency histogram (ms) Version p50 mean p95 p99 max base 1315 1198 2347 3454 10319 mglru 2559 1311 7399 12060 43758 fix 1119 926 2470 4211 6947 This series replaces the final non-selftest patchs from this series[1], which introduced a similar change (and a new MMU notifier) with KVM optimizations. I'll send a separate series (to Sean and Paolo) for the KVM optimizations. This series also makes proactive reclaim with MGLRU possible for KVM memory. I have verified that this functions correctly with the selftest from [1], but given that that test is a KVM selftest, I'll send it with the rest of the KVM optimizations later. Andrew, let me know if you'd like to take the test now anyway.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler fixes from Thomas Gleixner: - Plug a race between pick_next_task_fair() and try_to_wake_up() where both try to write to the same task, even though both paths hold a runqueue lock, but obviously from different runqueues. The problem is that the store to task::on_rq in __block_task() is visible to try_to_wake_up() which assumes that the task is not queued. Both sides then operate on the same task. Cure it by rearranging __block_task() so the the store to task::on_rq is the last operation on the task. - Prevent a potential NULL pointer dereference in task_numa_work() task_numa_work() iterates the VMAs of a process. A concurrent unmap of the address space can result in a NULL pointer return from vma_next() which is unchecked. Add the missing NULL pointer check to prevent this. - Operate on the correct scheduler policy in task_should_scx() task_should_scx() returns true when a task should be handled by sched EXT. It checks the tasks scheduling policy. This fails when the check is done before a policy has been set. Cure it by handing the policy into task_should_scx() so it operates on the requested value. - Add the missing handling of sched EXT in the delayed dequeue mechanism.

2024-11-03modpost: fix input MODULE_DEVICE_TABLE() built for 64-bit on 32-bit hostMasahiro Yamada
When building a 64-bit kernel on a 32-bit build host, incorrect input MODULE_ALIAS() entries may be generated. For example, when compiling a 64-bit kernel with CONFIG_INPUT_MOUSEDEV=m on a 64-bit build machine, you will get the correct output: $ grep MODULE_ALIAS drivers/input/mousedev.mod.c MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*110,*r*0,*1,*a*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*r*8,*a*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*14A,*r*a*0,*1,*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*145,*r*a*0,*1,*18,*1C,*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*110,*r*a*0,*1,*m*l*s*f*w*"); However, building the same kernel on a 32-bit machine results in incorrect output: $ grep MODULE_ALIAS drivers/input/mousedev.mod.c MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*110,*130,*r*0,*1,*a*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*r*8,*a*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*14A,*16A,*r*a*0,*1,*20,*21,*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*145,*165,*r*a*0,*1,*18,*1C,*20,*21,*38,*3C,*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*110,*130,*r*a*0,*1,*20,*21,*m*l*s*f*w*"); A similar issue occurs with CONFIG_INPUT_JOYDEV=m. On a 64-bit build machine, the output is: $ grep MODULE_ALIAS drivers/input/joydev.mod.c MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*0,*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*2,*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*8,*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*6,*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*k*120,*r*a*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*k*130,*r*a*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*k*2C0,*r*a*m*l*s*f*w*"); However, on a 32-bit machine, the output is incorrect: $ grep MODULE_ALIAS drivers/input/joydev.mod.c MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*0,*20,*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*2,*22,*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*8,*28,*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*6,*26,*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*k*11F,*13F,*r*a*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*k*11F,*13F,*r*a*m*l*s*f*w*"); MODULE_ALIAS("input:b*v*p*e*-e*1,*k*2C0,*2E0,*r*a*m*l*s*f*w*"); When building a 64-bit kernel, BITS_PER_LONG is defined as 64. However, on a 32-bit build machine, the constant 1L is a signed 32-bit value. Left-shifting it beyond 32 bits causes wraparound, and shifting by 31 or 63 bits makes it a negative value. The fix in commit e0e92632715f ("[PATCH] PATCH: 1 line 2.6.18 bugfix: modpost-64bit-fix.patch") is incorrect; it only addresses cases where a 64-bit kernel is built on a 64-bit build machine, overlooking cases on a 32-bit build machine. Using 1ULL ensures a 64-bit width on both 32-bit and 64-bit machines, avoiding the wraparound issue.

2024-11-03modpost: fix acpi MODULE_DEVICE_TABLE built with mismatched endiannessMasahiro Yamada
When CONFIG_SATA_AHCI_PLATFORM=m, modpost outputs incorect acpi MODULE_ALIAS() if the endianness of the target and the build machine do not match. When the endianness of the target kernel and the build machine match, the output is correct: $ grep 'MODULE_ALIAS("acpi' drivers/ata/ahci_platform.mod.c MODULE_ALIAS("acpi*:APMC0D33:*"); MODULE_ALIAS("acpi*:010601:*"); However, when building a little-endian kernel on a big-endian machine (or vice versa), the output is incorrect: $ grep 'MODULE_ALIAS("acpi' drivers/ata/ahci_platform.mod.c MODULE_ALIAS("acpi*:APMC0D33:*"); MODULE_ALIAS("acpi*:0601??:*"); The 'cls' and 'cls_msk' fields are 32-bit. DEF_FIELD() must be used instead of DEF_FIELD_ADDR() to correctly handle endianness of these 32-bit fields. The check 'if (cls)' was unnecessary; it never became NULL, as it was the pointer to 'symval' plus the offset to the 'cls' field.

2024-11-02Input: fix regression when re-registering input handlersDmitry Torokhov
Commit d469647bafd9 ("Input: simplify event handling logic") introduced code that would set handler->events() method to either input_handler_events_filter() or input_handler_events_default() or input_handler_events_null(), depending on the kind of input handler (a filter or a regular one) we are dealing with. Unfortunately this breaks cases when we try to re-register the same filter (as is the case with sysrq handler): after initial registration the handler will have 2 event handling methods defined, and will run afoul of the check in input_handler_check_methods(): input: input_handler_check_methods: only one event processing method can be defined (sysrq) sysrq: Failed to register input handler, error -22 Fix this by adding handle_events() method to input_handle structure and setting it up when registering a new input handle according to event handling methods defined in associated input_handler structure, thus avoiding modifying the input_handler structure.

2024-10-31mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizesVlastimil Babka
Since commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP boundaries") a mmap() of anonymous memory without a specific address hint and of at least PMD_SIZE will be aligned to PMD so that it can benefit from a THP backing page. However this change has been shown to regress some workloads significantly. [1] reports regressions in various spec benchmarks, with up to 600% slowdown of the cactusBSSN benchmark on some platforms. The benchmark seems to create many mappings of 4632kB, which would have merged to a large THP-backed area before commit efa7df3e3bb5 and now they are fragmented to multiple areas each aligned to PMD boundary with gaps between. The regression then seems to be caused mainly due to the benchmark's memory access pattern suffering from TLB or cache aliasing due to the aligned boundaries of the individual areas. Another known regression bisected to commit efa7df3e3bb5 is darktable [2] [3] and early testing suggests this patch fixes the regression there as well. To fix the regression but still try to benefit from THP-friendly anonymous mapping alignment, add a condition that the size of the mapping must be a multiple of PMD size instead of at least PMD size. In case of many odd-sized mapping like the cactusBSSN creates, those will stop being aligned and with gaps between, and instead naturally merge again.

2024-10-31vmscan,migrate: fix page count imbalance on node stats when demoting pagesGregory Price
When numa balancing is enabled with demotion, vmscan will call migrate_pages when shrinking LRUs. migrate_pages will decrement the the node's isolated page count, leading to an imbalanced count when invoked from (MG)LRU code. The result is dmesg output like such: $ cat /proc/sys/vm/stat_refresh [77383.088417] vmstat_refresh: nr_isolated_anon -103212 [77383.088417] vmstat_refresh: nr_isolated_file -899642 This negative value may impact compaction and reclaim throttling. The following path produces the decrement: shrink_folio_list demote_folio_list migrate_pages migrate_pages_batch migrate_folio_move migrate_folio_done mod_node_page_state(-ve) <- decrement This path happens for SUCCESSFUL migrations, not failures. Typically callers to migrate_pages are required to handle putback/accounting for failures, but this is already handled in the shrink code. When accounting for migrations, instead do not decrement the count when the migration reason is MR_DEMOTION. As of v6.11, this demotion logic is the only source of MR_DEMOTION.
