I currently have a partially- to mostly-working version of OpenAFS for
freebsd 4.x (I'm working with 4.4. hopefully vm will be mostly
compatible with other 4.x's) 

My biggest current problem is that mmap isn't working. cp seems to use
mmap, and it always ends up creating a file full of nulls. It appears as
though my getpages function is never being called, even though it seems
to be properly listed in my vnodeopv_entry_desc (and my other vnodeops
do get called)

source can be viewed at http://www.contrib.andrew.cmu.edu/~cg2v/freebsd-openafs

The interesting files here are osi_vnodeops.c and osi_module.c (which
does initialization; I know that what osi_module.c does is non-standard,
but I can't think of any other way to prevent the filesystem code from
registering if
the syscall installation fails) The afs_vop_read and afs_vop_getpages
files are extracted copies of those particular vnode ops, to make it
easier to examine them.

Any help will be appreciated.
