From 8d714f8aa34cf6a49b8d8d291ab01a59699604bd Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Tue, 31 Jul 2018 09:09:01 -0700 Subject: [PATCH] f2fs: avoid f2fs_bug_on() in cp_error case There is a subtle race condition to invoke f2fs_bug_on() in shutdown tests. I've confirmed that the last checkpoint is preserved in consistent state, so it'd be fine to just return error at this moment.
