Subject: f2fs: use SSR for warm node as well
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5b6c6be2d878bd7ec4dc2cb4e2a2da2779fe52ab;p=openwrt%2Fstaging%2Fblogic.git

f2fs: use SSR for warm node as well

We have had node chains, but haven't used it so far due to stale node blocks.
Now, we have crc|cp_ver in node footer and give random cp_ver at format time,
we can start to use it again.
