+
+In f2fs_iget(), we will check inode's first block address, if it is valid,
+we will set FI_FIRST_BLOCK_WRITTEN flag in inode.
+
+But we should only do this for regular inode, otherwise, like special
+inode, i_addr[0] is used for storing device info instead of block address,
+it will fail checking flow obviously.
+
+So for non-regular inode, let's skip verifying address and setting flag.
