This can cause a problem during readout if the VBIOS/GOP enabled the LUT in the pre CSC configuration. The current code blindly assigns the results of the readout to the degamma_lut, which will cause a failure during the next atomic_check() as we aren't expecting anything to be in degamma_lut since it's not visible to userspace.

[PATCH 5.10] ntfs: do not dereference a null ctx on error

by George Rurikov

From: George Ryurikov <g.ryurikov(a)securitycode.ru> Danila Chernetsov <listdansp(a)mail.ru> commit aa4b92c5234878d55da96d387ea4d3695ca5e4ab upstream. In ntfs_mft_data_extend_allocation_nolock(), if an error condition occurs prior to 'ctx' being set to a non-NULL value, avoid dereferencing the NULL 'ctx' pointer in error handling. Found by Linux Verification Center (linuxtesting.org) with SVACE.

[PATCH] HID: plantronics: Workaround for an unexcepted opposite volume key

by Wade Wang

Some Plantronics headset as the below send an unexcept opposite volume key's HID report for each volume key press after 200ms, like unecepted Volume Up Key following Volume Down key pressed by user. This patch adds a quirk to hid-plantronics for these devices, which will ignore the second unexcepted opposite volume key if it happens within 220ms from the last one that was handled. Plantronics EncorePro 500 Series (047f:431e) Plantronics Blackwire_3325 Series (047f:430c) The patch was tested on the mentioned model, it shouldn't affect other models, however, this quirk might be needed for them too. Auto-repeat (when a key is held pressed) is not affected per test result.

[PATCH] r8169: add tally counter fields added with RTL8125

by Heiner Kallweit

RTL8125 added fields to the tally counter, what may result in the chip dma'ing these new fields to unallocated memory. Therefore make sure that the allocated memory area is big enough to hold all of the tally counter values, even if we use only parts of it.

Regression in 6.11.2

by Mario Limonciello

Hi, commit 872b8f14d772 ("drm/amd/display: Validate backlight caps are sane") was added to stable trees to fix a brightness problem on one laptop on a buggy firmware but with how aggressive it was it caused a problem on another. Fortunately the problem on the other was already fixed in 6.12 though! commit 87d749a6aab7 ("drm/amd/display: Allow backlight to go below `AMDGPU_DM_DEFAULT_MIN_BACKLIGHT`") Can that commit please be brought everywhere that 872b8f14d772 went? Thanks!

The only disadvantage of zsmalloc in comparison is the dependency on MMU, and zbud is a more common option for !MMU as it was the default zswap allocator for a long time. Historically, zsmalloc had worse latency than zbud and z3fold but offered better memory savings. This is no longer the case as shown by a simple recent analysis [1]. That analysis showed that z3fold does not have any advantage over zsmalloc or zbud considering both performance and memory usage. In a kernel build test on tmpfs in a limited cgroup, z3fold took 3% more time and used 1.8% more memory. The latency of zswap_load() was 7% higher, and that of zswap_store() was 10% higher. Zsmalloc is better in all metrics. Moreover, z3fold apparently has latent bugs, which was made noticeable by a recent soft lockup bug report with z3fold [2]. Switching to zsmalloc not only fixed the problem, but also reduced the swap usage from 6~8G to 1~2G. Other users have also reported being bitten by mistakenly enabling z3fold. Other than hurting users, z3fold is repeatedly causing wasted engineering effort. Apart from investigating the above bug, it came up in multiple development discussions (e.g. [3]) as something we need to handle, when there aren't any legit users (at least not intentionally). The natural course of action is to deprecate z3fold, and remove in a few cycles if no objections are raised from active users. Next on the list should be zbud, as it offers marginal latency gains at the cost of huge memory waste when compared to zsmalloc. That one will need to wait until zsmalloc does not depend on MMU. Rename the user-visible config option from CONFIG_Z3FOLD to CONFIG_Z3FOLD_DEPRECATED so that users with CONFIG_Z3FOLD=y get a new prompt with explanation during make oldconfig. Also, remove CONFIG_Z3FOLD=y from defconfigs.
