Oh, and before I forget: this option is defined in /sys/conf/NOTES as
well (a pure #ifdef in source code is not enough, of course :-)
# Experimental support for large MS-DOS filesystems.
# WARNING: This uses at least 32 bytes of kernel memory (which is not
# reclaimed until the FS is unmounted) for each file on disk to map
# between the 32-bit inode numbers used by VFS and the 64-bit
# numbers used internally by msdosfs. This is only safe to use in
# controlled situations (e.g. read-only FS with less than 1 million
# Since the mappings do not persist across unmounts (or reboots), these
# filesystems are not suitable for exporting through NFS, or any other
# application that requires fixed inode numbers.
