# 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 # Depends on: TMPFS [=y] && 64BIT [=y] # Location: # -> File systems # -> Pseudo filesystems # -> Tmpfs virtual memory file system support (former shm fs) (TMPFS [=y]) # # # CONFIG_TMPFS_INODE64=y
