Hi Hugh,

But I can see that the lack of reinitialization of entry.val here
does raise doubt and confusion.  A better tidyup would be to remove
the initialization of swp_entry_t entry from its onstack declaration,
and do it at the again label instead.

I just want to avoid allocating page in add_swap_count_continuation()
for non clear reason, as you see, which is not a bug fix.

Thanks,
