## Before my package is installed:
$ dpkg -l drbd-utils | grep RAID

utilities)
$ sudo losetup --find --show /.loop
/dev/loop0
$ sudo drbdadm create-md r0
initializing activity log
NOT initializing bitmap
Fix works in kernel 5.0 as well:
(k)rafaeldtinoco@drbdfix:~$ sudo dd if=/dev/zero of=/.loop bs=1M count=1024
