-
- This means, that no mapping of file blocks to disk blocks is possible (*)
- and that therefore the bmap function is not available. The kernel uses
- bmap internally for things like demand-paging, swapping, etc. The only
- user-mode application that uses bmap is LILO.
-
- Thus, not having bmap support only means that you can't run executables
- from that FS, that you can't put a swap file on it and that no LILO boot
- files can reside there.
-
- (*) This happens whenever the disk data area starts at an odd sector or
- the cluster size is not a multiple of 1 kB.
