It applies to scsi subsystem, so shouldn't affect drbd, i think.

I've got 2+ years of stable operation of drbd 8.4.x with this patch applied.
The boxes were exporting drbd devices through iscsi, the usual thing.
No lockups, corruptions etc whatsoever. Load is relatively high, nodes 
1year+, so i think it does not hurt drbd.
