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