Take a look at sys_chmod() for some ideas how it should work. The kernel
source most easily available to me appears to go through some hoops with
struct iattr newattrs, performs the mode masking operations on the
structure, then uses notify_change() to perform the modifications.
(This is probably to assist tools such as the file access monitor, used
in many explorer.exe-work-alikes.)

I hope this helps...
