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