From: Chao Yu <yuchao0@xxxxxxxxxx>
After fsync, filesystem should guarantee inode metadata including
creation time being persisted, so even after sudden power-cut, during
mount, we should recover i_crtime_{,nsec} fields correctly, in order
to not loss those meta info.
So adding this testcase to check whether generic filesystem can
guarantee that.
Note that, it needs inode creation time support on specified filesystem.
