Re: [PATCH v4 05/19] mm: Rename memfd_luo to shmem_luo

[sashiko-bot@kernel.org]

> Rename the memfd Live Update file handler from memfd_luo to shmem_luo,
> including the source file, its KHO ABI header, its documentation and its
> Kconfig option (CONFIG_LIVEUPDATE_MEMFD to CONFIG_LIVEUPDATE_SHMEM).
> 
> The handler preserves shmem files. Today those are memfds, but following
> commits extend it to other files on tmpfs mounts, for which the memfd
> name is confusing. Memfds created with MFD_HUGETLB are hugetlbfs files
> and would need a separate handler, so name this one after its backing
> filesystem instead.
> 
> Don't change the compatible string of the handler, "memfd-v2". It is
> matched against the preserved state from the previous kernel, so
> changing it would break live updates from kernels that use the old
> name. The serialized format doesn't change either.
> 
> Also clarify in the documentation that memfd means a memfd created
> without MFD_HUGETLB, and name the ABI documentation after the handler.
> 
> No functional change intended.
