Nit picking.  It is quite possible to add code to the kernel, compile
it as a module and load into the existing kernel without rebuilding
bzImage or rebooting.  This only works if the add on code has *NO*
changes to the main kernel, several drivers are shipped this way
because they are completely standalone.  However XFS requires changes
to the base kernel code as well as the XFs code itself so in this case
you do need to compile bzImage and reboot.
