The current mTHP swapin path have several problems. It may potentially hang, may cause redundant faults due to false positive swap cache lookup, and it will involve at least 4 Xarray tree walks (get order, get order again, confirm swap, insert folio). And for !CONFIG_TRANSPARENT_HUGEPAGE builds, it will performs some mTHP related checks. This series fixes all of the mentioned issues, and the code should be more robust and prepared for the swap table series. Now tree walks is reduced to twice (get order & confirm, insert folio), !CONFIG_TRANSPARENT_HUGEPAGE build overhead is also minimized, and comes with a sanity check now. The performance is slightly better after this series, sequential swap in of 24G data from ZRAM, using transparent_hugepage_tmpfs=always (24 samples each): Before: Avg: 10.67s, stddev: 0.04 After patch 1: Avg: 10.49s, stddev: 0.04 After patch 2: Avg: 10.42s, stddev: 0.05 After patch 3: Avg: 10.45s, stddev: 0.05 After patch 4: Avg: 10.49s, stddev: 0.04 After patch 5: Avg: 9.67s, stddev: 0.03 After patch 6: Avg: 9.67s, stddev: 0.04 After patch 7: Avg: 9.68s, stddev: 0.05 After patch 8: Avg: 9.66s, stddev: 0.04 Several patches improve the performance by a little, which is about ~10% faster in total. Build kernel test showed very slightly improvement, testing with make -j48 with defconfig in a 768M memcg also using ZRAM as swap, and transparent_hugepage_tmpfs=always (6 test runs): Before: avg: 3353.66s, stddev: 33.73 After patch 1: avg: 3354.19s, stddev: 42.54 After patch 2: avg: 3364.16s, stddev: 52.74 After patch 3: avg: 3355.73s, stddev: 36.17 After patch 4: avg: 3352.78s, stddev: 39.80 After patch 5: avg: 3355.19s, stddev: 50.78 After patch 6: avg: 3333.63s, stddev: 32.50 After patch 7: avg: 3297.70s, stddev: 38.93 After patch 8: avg: 3302.35s, stddev: 50.61 This patch (of 8): The current swap-in code assumes that, when a swap entry in shmem mapping is order 0, its cached folios (if present) must be order 0 too, which turns out not always correct. The problem is shmem_split_large_entry is called before verifying the folio will eventually be swapped in, one possible race is: CPU1 CPU2 shmem_swapin_folio /* swap in of order > 0 swap entry S1 */ folio = swap_cache_get_folio /* folio = NULL */ order = xa_get_order /* order > 0 */ folio = shmem_swap_alloc_folio /* mTHP alloc failure, folio = NULL */ <... Interrupted ...> shmem_swapin_folio /* S1 is swapped in */ shmem_writeout /* S1 is swapped out, folio cached */ shmem_split_large_entry(..., S1) /* S1 is split, but the folio covering it has order > 0 now */ Now any following swapin of S1 will hang: `xa_get_order` returns 0, and folio lookup will return a folio with order > 0. The `xa_get_order(&mapping->i_pages, index) != folio_order(folio)` will always return false causing swap-in to return -EEXIST. And this looks fragile. So fix this up by allowing seeing a larger folio in swap cache, and check the whole shmem mapping range covered by the swapin have the right swap value upon inserting the folio. And drop the redundant tree walks before the insertion. This will actually improve performance, as it avoids two redundant Xarray tree walks in the hot path, and the only side effect is that in the failure path, shmem may redundantly reallocate a few folios causing temporary slight memory pressure. And worth noting, it may seems the order and value check before inserting might help reducing the lock contention, which is not true. The swap cache layer ensures raced swapin will either see a swap cache folio or failed to do a swapin (we have SWAP_HAS_CACHE bit even if swap cache is bypassed), so holding the folio lock and checking the folio flag is already good enough for avoiding the lock contention. The chance that a folio passes the swap entry value check but the shmem mapping slot has changed should be very low.

[PATCH v2] zynq_fpga: use sgtable-based scatterlist wrappers

by Marek Szyprowski

Use common wrappers operating directly on the struct sg_table objects to fix incorrect use of statterlists related calls. dma_unmap_sg() function has to be called with the number of elements originally passed to the dma_map_sg() function, not the one returned in sgtable's nents.

[PATCH 1/1] Drivers: hv: Select CONFIG_SYSFB only if EFI is enabled

by mhkelley58＠gmail.com

From: Michael Kelley <mhklinux(a)outlook.com> Commit 96959283a58d ("Drivers: hv: Always select CONFIG_SYSFB for Hyper-V guests") selects CONFIG_SYSFB for Hyper-V guests so that screen_info is available to the VMBus driver to get the location of the framebuffer in Generation 2 VMs. However, if CONFIG_HYPERV is enabled but CONFIG_EFI is not, a kernel link error results in ARM64 builds because screen_info is provided by the EFI firmware interface. While configuring an ARM64 Hyper-V guest without EFI isn't useful since EFI is required to boot, the configuration is still possible and the link error should be prevented. Fix this by making the selection of CONFIG_SYSFB conditional on CONFIG_EFI being defined. For Generation 1 VMs on x86/x64, which don't use EFI, the additional condition is OK because such VMs get the framebuffer information via a mechanism that doesn't use screen_info.

[PATCH AUTOSEL 6.15 1/8] Revert "ACPI: battery: negate current when discharging"

by Sasha Levin

From: "Rafael J. Wysocki" <rafael.j.wysocki(a)intel.com> [ Upstream commit de1675de39aa945bad5937d1fde4df3682670639 ] Revert commit 234f71555019 ("ACPI: battery: negate current when discharging") breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud. Perhaps it breaks more, but those are the two that have been tested. Reported-by: Matthew Schwartz <matthew.schwartz(a)linux.dev> Closes: https://lore.kernel.org/linux-acpi/87C1B2AF-D430-4568-B620-14B941A8ABA4@lin… Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki(a)intel.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- **YES**, this commit should be backported to stable kernel trees. ## Extensive Explanation: ### 1. **Critical Userspace Regression Fix** This revert fixes a critical regression that breaks userspace applications. The commit message explicitly states that the original change "breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud." This is a clear violation of the kernel's "no userspace regressions" rule, which is one of the most fundamental principles in kernel development. ### 2. **Code Analysis Shows ABI Change** Looking at the code changes: ```c // The problematic code that was added (and is now being removed): if (psp == POWER_SUPPLY_PROP_CURRENT_NOW && (battery->state & ACPI_BATTERY_STATE_DISCHARGING) && acpi_battery_handle_discharging(battery) == POWER_SUPPLY_STATUS_DISCHARGING) val->intval = -val->intval; ``` This code was changing the sign of the current value when discharging, which altered the userspace-visible ABI. Even if the original behavior didn't match documentation, changing it broke existing applications that depended on the long-standing behavior. ### 3. **Simple and Safe Revert** The commit is a clean revert that: - Removes the problematic sign negation logic - Restores the original behavior that userspace applications expect - Is self-contained to the `acpi_battery_get_property()` function - Has minimal risk of introducing new issues ### 4. **Meets Stable Kernel Criteria** According to stable kernel rules, this commit qualifies because it: - **Fixes a real bug** that users are hitting (broken battery monitoring in Steam and MangoHud) - **Is obviously correct** (it's a revert of a change that broke userspace) - **Is small and contained** (only affects the ACPI battery property reporting) - **Has been tested** (the reporter confirmed the issue) - **Fixes a regression** (restores previous working behavior) ### 5. **Comparison to Similar Commits** Looking at the historical commits marked with "Backport Status: YES", they share similar characteristics: - Fix actual problems affecting users - Are relatively small and contained changes - Don't introduce new features or architectural changes - Focus on fixing specific issues This revert fits perfectly into this pattern as it's fixing a specific userspace compatibility issue without introducing any new functionality. ### 6. **Timing Considerations** The original problematic commit (234f71555019) was from May 8, 2025, and this revert is from July 3, 2025. If the original commit made it into any stable releases, those stable trees would need this revert to prevent userspace breakage. ### Conclusion: This is a textbook example of a commit that should be backported to stable kernels. It fixes a userspace regression, is minimal in scope, carries very low risk, and restores previously working behavior that applications depend on. The fact that it's a revert of a problematic change makes it even more suitable for stable backporting. drivers/acpi/battery.c | 19 +++---------------- 1 file changed, 3 insertions(+), 16 deletions(-) diff --git a/drivers/acpi/battery.c b/drivers/acpi/battery.c index 93bb1f7d90986..6760330a8af55 100644 --- a/drivers/acpi/battery.c +++ b/drivers/acpi/battery.c @@ -243,23 +243,10 @@ static int acpi_battery_get_property(struct power_supply *psy, break; case POWER_SUPPLY_PROP_CURRENT_NOW: case POWER_SUPPLY_PROP_POWER_NOW: - if (battery->rate_now == ACPI_BATTERY_VALUE_UNKNOWN) { + if (battery->rate_now == ACPI_BATTERY_VALUE_UNKNOWN) ret = -ENODEV; - break; - } - - val->intval = battery->rate_now * 1000; - /* - * When discharging, the current should be reported as a - * negative number as per the power supply class interface - * definition. - */ - if (psp == POWER_SUPPLY_PROP_CURRENT_NOW && - (battery->state & ACPI_BATTERY_STATE_DISCHARGING) && - acpi_battery_handle_discharging(battery) - == POWER_SUPPLY_STATUS_DISCHARGING) - val->intval = -val->intval; - + else + val->intval = battery->rate_now * 1000; break; case POWER_SUPPLY_PROP_CHARGE_FULL_DESIGN: case POWER_SUPPLY_PROP_ENERGY_FULL_DESIGN: -- 2.39.5
