+# CONFIG_TMPFS_INODE64:
+# 
+# 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.
+# 
+# If unsure, say N.
+# 
+# Symbol: TMPFS_INODE64 [=n]
+# Type  : bool
+# Defined at fs/Kconfig:204
+#   Prompt: Use 64-bit ino_t by default in tmpfs
