This is kind of a success report:
I managed to build and run the client on both i686 and x86_64.
The former just worked. x86_64 made some trouble, though:
There are many 32bit syscall numbers missing in the kernel headers.
A workaround for this seems to be in CVS now, similar to what I did to
get the module built: grab the numbers from the i686 headers and add
#defines for them.
With this hack, the module built but couldn't be loaded: "libafs: Unknown
symbol tasklist_lock". Indeed, this seems to have been removed recently.
I simply removed all the "read_[un]lock(&tasklist_lock);" statements,
and the result is a client that apparently works under light load,
but I'm not at all sure that this is the right solution. Any hints?
Try this (untested) patch. It's not great, but it should get you going for
now...
