Subject: [PATCH] scsi_debug: Add OPTIMAL TRANSFER LENGTH GRANULARITY option.
Date: Sat,  7 Jan 2017 09:50:26 +0100	[thread overview]
Message-ID: <1483779027-10052-1-git-send-email-lherbolt@redhat.com> (raw)
In-Reply-To: <lherbolt@redhat.com>

Hello,
I have been playing with scsi_debug and found that there is no way how to change the
minimum_io_size (OPTIMAL TRANSFER LENGTH GRANULARITY reported by VPD 0xb0).

The current module has minimum_io_size always set to physical_block_size.
So here comes a small patch which add a new option to this module to be
able to set it independently to the physical_block_size. Default behavior
is to keep the minimum_io_size equal to the physical_block_size.

Lukas
