Hi all,

Commit

  48248e468270 ("mm: hugetlb: add huge page size param to set_huge_pte_at()")

is missing Signed-off-bys from its author and committer.

It looks like the commit message has been truncated.

Ah, thanks.  The changelog has a stray ^---$:

: If CONFIG_DEBUG_VM is enabled, we do at least get a BUG(), but otherwise,
: it will dereference a bad pointer in page_folio():
: 
:     static inline struct folio *hugetlb_swap_entry_to_folio(swp_entry_t entry)
:     {
:         VM_BUG_ON(!is_migration_entry(entry) && !is_hwpoison_entry(entry));
: 
:         return page_folio(pfn_to_page(swp_offset_pfn(entry)));
:     }
: 
: 
: Fix

<chomp>

That's actually from the [0/n] intro, which I pasted into the [1/n]
changelog.

It gets through my scripts OK
(https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-hugetlb-add-huge-page-size-param-to-set_huge_pte_at.patch),
but it looks like git-quiltimport did the deed.

Let me add a check for that...

I don't think there is any action for me here? (except possibly, never use 3
dashes in a row on any future email correspondence). Shout if you need anything.

I didn't trim at the ^---$ correctly.  I guess we should check for more
than one "^---$.
