Hi Jeremy, thank you for looking at this!

With the argumentation used above, I could cast almost all
ints in the asprintf format, because most of the values will
never be negative. However it was my original intention to not
have to cast all the values inside the asprintf format. :)
Also, nearly none of the values will ever  be in the range where
unsigned/signed does matter. The only exception I see is theoretically
the write/pwrite/read/pread call, that returns a size_t as the
number of bytes that have been transferred. And even there
it's unlikely I'll hit the borders. 

So in this patch, I am using a size_t for write,read,pread,pwrite,
and cast it to unsigned int.

Additionally, in this patch I've added the 
vfs_fn_pointer for the smb_traffic_analyzer_rmdir function to 
vfs_smb_traffic_analyzer_fns. I've missed that in the first
