From 5d7881cadf64277c1e212721073eaabfade12f66 Mon Sep 17 00:00:00 2001 From: Yunlei He Date: Wed, 7 Mar 2018 16:22:50 +0800 Subject: f2fs: Don't overwrite all types of node to keep node chain Currently, we enable node SSR by default, and mixed different types of node segment to do SSR more intensively. Although reuse warm node is not allowed, warm node chain will be destroyed by errors introduced by other types node chain. So we'd better forbid reusing all types of node to keep warm node chain.
