From 9cf43a360450ddd758b0021d1b55f1cc5643b9ed Mon Sep 17 00:00:00 2001 From: "Matthew R. Ochs" Date: Wed, 21 Jun 2017 21:16:13 -0500 Subject: scsi: cxlflash: Support LUN provisioning Adopt the SISLite AFU LUN provisioning capability to allow future CXL Flash adapters the ability to better manage storage. Update the SISLite header with the changes necessary to support LUN provision operations and create a host ioctl interface for user LUN management software. Also update the cxlflash documentation to describe this new host ioctl. Signed-off-by: Matthew R. Ochs Signed-off-by: Uma Krishnan Signed-off-by: Martin K.
