This is currently the only atomic_long_t variable initialized by
ATOMIC_INIT macro found in the kernel by using
`grep -r atomic_long_t | grep ATOMIC_INIT`

This was introduced in 6e1fa555ec77, in which we modified
the type of zswap_stored_pages to atomic_long_t,
but didn't change the initialization.

Fixes: 6e1fa555ec77 ("mm: zswap: modify zswap_stored_pages to be atomic_long_t")

Something for the future: if you send a v2, indicate that in the patch 
subject ("[PATCH v2]") and ideally, describe the change since v1 under 
the "---", and don't send it as reply to the original patch.

the correct way to reference to commits ids even in text is the format 
you use below.

But here it's sufficient to not be repetitive and simply say

"We changed the type of zswap_stored_pages to be an atomic_long_t, but 
didn't change the initialization."
