Subject: mm: zswap: use ATOMIC_LONG_INIT to initialize zswap_stored_pages
Date: Wed, 26 Feb 2025 23:32:43 +0800
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.
