What loaded it?  It doesn't autoload.

I have a rawhide VM here too, it has nothing related to zram
configuration, and the module isn't loaded.  Every machine I have is
like this.

[jwboyer@localhost ~]$ lsmod | grep zram
[jwboyer@localhost ~]$ dmesg | grep zram
[jwboyer@localhost ~]$ ls /dev/zram*
ls: cannot access /dev/zram*: No such file or directory
[jwboyer@localhost ~]$ uname -a
Linux localhost.localdomain 3.15.0-0.rc2.git0.1.fc21.x86_64 #1 SMP Mon

[jwboyer@localhost ~]$ modinfo zram

[jwboyer@localhost ~]$ rpm -q systemd

[jwboyer@localhost ~]$


So, I guess you need to figure out what loaded the zram module.
