194	  Extended attributes are name:value pairs associated with inodes by

207	default n
208	help
209	  tmpfs has historically used only inode numbers as wide as an unsigned
210	  int. In some cases this can cause wraparound, potentially resulting
211	  in multiple files with the same inode number on a single device. This
212	  option makes tmpfs use the full width of ino_t by default, without
213	  needing to specify the inode64 option when mounting.
214
215	  But if a long-lived tmpfs is to be accessed by 32-bit applications so
216	  ancient that opening a file larger than 2GiB fails with EINVAL, then
217	  the INODE64 config option and inode64 mount option risk operations
218	  failing with EOVERFLOW once 33-bit inode numbers are reached.
219
220	  To override this configured default, use the inode32 or inode64
221	  option when mounting.
222
223	  If unsure, say N.
