From 83d5d6f66b375f21bee4c2e17178f7c073a66301 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Tue, 28 May 2013 12:25:47 +0900 Subject: f2fs: cover cp_file information with ilock If a file is linked with other files, it should be checkpointed at every fsync calls. For this, we use set_cp_file() with FADVISE_CP_BIT, but previously we didn't cover the flag by the global lock. This patch fixes that the inode page stores this correctly.
