alloc_tag: avoid implicit padding in uapi

2026-09-26T20:55:10Z

The implied padding causes a harmless warning when testing the uapi headers with -Wpadded that could in theory indicate incompatibilities or data leaks: ./usr/include/linux/alloc_tag.h:41:1: error: padding struct size to alignment boundary with 7 bytes [-Werror=padded] The code here is fine, but it's better to make the padding explicit and avoid the warning here.

Input: document that no new LED codes should be added

2026-09-14T00:25:16Z

Add a comment to input-event-codes.h clarifying that no new LED definitions should be added to the input subsystem. The existing LED_* definitions are legacy and grandfathered for backwards compatibility with userspace via evdev. Any new LED indicators should instead use the dedicated LED subsystem.

drm/amdgpu/userq: fix struct drm_amdgpu_info_device padding for 32bit compile

2026-09-02T21:02:23Z

need to pad before __u64 tcc_disabled_mask variable. This patch fixes 64bit Kernel + 32 bit mesa combination. But at the same time it will break 32bit Kernel(using this patch) + older 32bit mesa(not using this patch). This issue was discussd with alexander.deucher@amd.com, christian.koenig@amd.com and pierre-eric.pelloux-prayer@amd.com. Currently today 32 bit kernel + 32 bit userspace and 64 bit kernel and 64 bit userspace work. Mixed 64 bit kernel and 32 bit userspace is currently broken. Since 32 bit kernel and userspace is probably pretty rare these days and the data affected by this is not critical, Hence we can go ahead with this patch.

RDMA/bnxt_re: Avoid exposing umdbr to userspace

2026-09-02T13:27:35Z

The umdbr field in struct bnxt_re_db_region returns the raw unmapped PCI BAR address of the doorbell region. Avoid sharing this field to the userspace. Change this to a reserved field and stop populating it, keeping the ABI layout and size unchanged for existing binaries.

configfs: move CONFIGFS_MAGIC definition to magic.h

IMA shouldn't measure or appraise configfs, but currently does because it's missing from the default exclusion policies. Move CONFIGFS_MAGIC to magic.h to expose the file system's magic to IMA, as well as other userland applications.
