[PATCH] jffs2: fix kernel BUG in jffs2_sum_write_sumnode on empty summary

[eltavine]

Hi Shuai,

> Suggested-by: eltavine <me at eltavine.com>

I'd like to clarify the code authorship of this patch before it is
applied.

I posted an RFC containing this fix on October 15, before your
November 5 submission:

https://lore.kernel.org/linux-mtd/20261015145341.34322-1-me@eltavine.com/

My RFC already replaced JFFS2_WARNING() and BUG() in the empty-summary
branch with dbg_summary(), jffs2_sum_disable_collecting(c->summary),
and goto out. The core control flow and state change are the same in
both patches; the differences in the hunk are the expanded comment
and the debug message wording.

Since the RFC included the implementation, Suggested-by does not fully
reflect my code contribution. Could you preserve my authorship with
an in-body author line in the next revision:

    From: eltavine <me at eltavine.com>

and retain my original sign-off:

    Signed-off-by: eltavine <me at eltavine.com>

followed by your sign-off for your updates and submission?

If there are additional implementation contributions I have overlooked,
please point them out so that we can accurately reflect both of our
contributions. I support getting the fix merged and would like the
code authorship clarified as part of the next revision.

Thanks,
eltavine
