After fsync, filesystem should guarantee inode metadata including i_flags being persisted, so even after sudden power-cut, during mount, we should recover i_flags fields correctly, in order to not loss those meta info. So adding this testcase to check whether generic filesystem can guarantee that. We only check below attribute modification which most filesystem supports: - no atime updates (A) - secure deletion (s) - synchronous updates (S) - undeletable (u) Signed-off-by: Chao Yu <yuchao0@huawei.com> Reviewed-by: Eryu Guan <guaneryu@gmail.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
