No, the problem is that since LFS has some different on-disk storage
and I/O requirements, the generic "getpages" and "putpages" routines
won't work for it.  Thus it needs its own set of getpages/putpages
routines.

...and, it could be reasonably argued that LFS shares "too much" code
with UFS these days...
