4 Subject: [PATCH 53/53] tests: Set optimal blocks to 64 for scsi_debug devices
6 The Linux kernel 4.5 changed the optimal blocks count from 64 to 1024
7 This causes tests using scsi_debug devices to fail because of alignment
8 issues. Set the opt_blks to 64 so that we have consistent behavior
11 (cherry picked from commit bd2664285e4014d2d4c80cee3e87609272e1fca9)
