docs/mm: clarify that we are not looking for LLM generated content

2026-06-23T20:31:45+00:00

Let's make it clear that we are not looking for LLM generated content from contributors not familiar with the details of MM, as it shifts the real work onto reviewers.

Pull liveupdate updates from Mike Rapoport: "Kexec Handover (KHO): - make memory preservation compatible with deferred initialization of the memory map Live Update Orchestrator (LUO): - add LIVEUPDATE_SESSION_GET_NAME ioctl and parameter verification for LIVEUPDATE_IOCTL_CREATE_SESSION ioctl - documentation updates for liveupdate=on command line option, systemd support and the current compatibility status - remove the fixed limits on the number of files that can be preserved within a single session, and the total number of sessions managed by the LUO Misc fixes: - reference count incoming File-Lifecycle-Bound (FLB) data so it cannot be freed while a subsystem is still using it - fixes for a TOCTOU race in luo_session_retrieve(), a use- after-free in the file finish and unpreserve paths, concurrent session mutations during reboot and serialization on preserve_context kexec - make sure ioctls for incoming LUO sessions are blocked for outgoing sessions and vice versa - make sure KHO scratch size is always aligned by CMA_MIN_ALIGNMENT_BYTES - fix memblock tests build issue introduced by KHO changes" * tag 'liveupdate-v7.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/liveupdate/linux: (36 commits) liveupdate: Document that retrieve failure is permanent docs: memfd_preservation: fix rendering of ABI documentation selftests/liveupdate: Add stress-files kexec test selftests/liveupdate: Add stress-sessions kexec test selftests/liveupdate: Test session and file limit removal liveupdate: Remove limit on the number of files per session liveupdate: Remove limit on the number of sessions liveupdate: defer session block allocation and physical address setting kho: add support for linked-block serialization liveupdate: Extract luo_session_deserialize_one helper liveupdate: Extract luo_file_deserialize_one helper liveupdate: register luo_ser as KHO subtree liveupdate: centralize state management into struct luo_ser liveupdate: avoid mixing cleanup guards with goto in luo_session_retrieve_fd liveupdate: change file_set->count type to u64 for type safety liveupdate: Remove unused ser field from struct luo_session liveupdate: fix u-a-f in luo_file_unpreserve_files() and luo_file_finish() liveupdate: block session mutations during reboot liveupdate: fix TOCTOU race in luo_session_retrieve() liveupdate: skip serialization for context-preserving kexec ...

docs: memfd_preservation: fix rendering of ABI documentation

2026-06-07T05:40:16+00:00

The "memfd Live Update ABI" section in include/linux/kho/abi/memfd.h currently does not render in the exported documentation. This is because it should not include the "DOC:" in its reference. Drop it to ensure correct rendering. Tested by running make htmldocs.
