copy_to_user() different in 2.6?

[Timur Tabi <timur.tabi@xxxxxxxxxxx>]

Is there anything different about copy_to_user() in the 2.6 kernels?  I 
have a driver which works fine in 2.4, but the copy_to_user() function 
doesn't appear to work when in 2.6.  It doesn't return an error code, 
but my user-space code doesn't see any of the data that was supposed to 
be copied.  The behavior is exactly as if I never called copy_to_user().
