+         tmpfs has historically used only inode numbers as wide as an unsigned
+         int. In some cases this can cause wraparound, potentially resulting
+         in multiple files with the same inode number on a single device. This
+         option makes tmpfs use the full width of ino_t by default, without
+         needing to specify the inode64 option when mounting.
+
+         But if a long-lived tmpfs is to be accessed by 32-bit applications so
+         ancient that opening a file larger than 2GiB fails with EINVAL, then
+         the INODE64 config option and inode64 mount option risk operations
+         failing with EOVERFLOW once 33-bit inode numbers are reached.
+
+         To override this configured default, use the inode32 or inode64
+         option when mounting.
