[ Upstream commit 1174abfd8309f4c47d454734233aa3b694560e10 ]
As description in commit "f2fs: don't drop any page on f2fs_cp_error() case":
"We still provide readdir() after shtudown, so we should keep pages to avoid additional IOs."
In order to provider lastest directory structure, let's keep dentry pages in cache after fs shutdown.
