+Subject: mkfs: fix filesize function compilation error on 32-bit archs
+
+Commit 73fb78e5ee89 changed the return type of filesize() from long to
+off_t, without changing the corresponding earlier declaration of the
+function.
+
+On 32-bit archs this breaks compilation as the off_t type is 8 bytes
+(since the unit is compiled with -D_FILE_OFFSET_BITS=64) and that is
+causing a conflicting type mismatch with the long type declaration.
+
+Fixes: 73fb78e5ee89 ("mkfs: support copying in large or sparse files")
