It might not be.  Some distributions include modules in the initial
ramdisk, and load the module from the initrd, simply dropping the
module in /lib/modules/<kver>/... might not be enough.  So recreating
the initrd and then rebooting might be enough.

Certainly if you drop it there on a running kernel, if you don't
unload the module (before unmounting all of your ext4 file systems),
and then reload the module, *definitely* just copying a module into
/lib/modules.... without making sure the module is reloaded, you'll
still have the old module.
