Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

Nope.
That tells you that modprobe *would* likely load this,
if you would do modprobe drbd *now*.
It does not tell you what you currently have loaded.

#cat /proc/drbd
#grep . /sys/module/drbd/*version

#rmmod drbd; modprobe drbd; cat /proc/drbd
