Given that I never encountered nor heard of a problem with samba serving
files, I would say you have a problem in your module. I would make sure
that you handle correctly all the seek and tell functions, and run the
samba4 torture suite to see if there is any problem. Probably the best
thing is to adapt the vfstest utility to do an extensive test of
filesystem returns (best thing would be to do that in a dual mode using
posix vfs on one side an your custom file system on other side and stop
on differences. Such a contribution would be great imho.

Simo.
