When building htmldocs on Linus' tree, there are inline emphasis warnings
on include/linux/highmem.h:
Documentation/vm/highmem:166: ./include/linux/highmem.h:154: WARNING: Inline emphasis start-string without end-string.
Documentation/vm/highmem:166: ./include/linux/highmem.h:157: WARNING: Inline emphasis start-string without end-string.
These warnings above are due to comments in code example of
*kmap_local_folio() are enclosed by double dash (--) instead of prefixed
with comment symbol (#).
Fix these warnings by indenting the code example with literal block
indentation and prefixing comments inside the example with #.

Nice catch.

As Willy said these are for kmap_atomic()

I'd rather see '//' used since this is C code and it makes the output
consistent with C syntax rather than mixing shell and C.
Thanks for the fixup!
