+Subject: [PATCH] fix up check for hardlinks always false if inode > 0xFFFFFFFF
+
+Since commit [382ed4a1 e2fsck: use proper types for variables][1]
+applied, it used ext2_ino_t instead of ino_t for referencing inode
+numbers, but the type of is_hardlink's `ino' should not be instead,
+The ext2_ino_t is 32bit, if inode > 0xFFFFFFFF, its value will be
+truncated.
+
+Add a debug printf to show the value of inode, when it check for hardlink
+files, it will always return false if inode > 0xFFFFFFFF

+Here is debug message:

+
+The length of ext2_ino_t is 32bit (typedef __u32 __bitwise ext2_ino_t;),
+and ino_t is 64bit on 64bit system (such as x86-64), recover `ino' to ino_t.
