Subject: [PATCH] f2fs: remove unneeded set_cold_node()
Date: Fri, 9 Mar 2018 14:24:22 +0800 [thread overview]
Message-ID: <20180309062422.71686-1-yuchao0@huawei.com> (raw)
When setting COLD_BIT_SHIFT flag in node block, we only need to call
set_cold_node() in new_node_page() and recover_inode_page() during
node page initialization. So remove unneeded set_cold_node() in other
places.
