From 250f35d78bcc0e9291690ab3dc26917d0dc144a3 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Tue, 8 Nov 2022 17:59:34 -0800 Subject: [PATCH] FROMGIT: f2fs: allow to read node block after shutdown If block address is still alive, we should give a valid node block even after shutdown. Otherwise, we can see zero data when reading out a file.
