209 tmpfs has historically used only inode numbers as wide as an unsigned

212 option makes tmpfs use the full width of ino_t by default, without

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.
