From 0217da08c1b904be49ac141442bbc1671d3630e7 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Fri, 7 Apr 2023 15:05:47 -0500 Subject: [PATCH] scsi: target: Rename sbc_ops to exec_cmd_ops The next patches allow us to call the block layer's pr_ops from the backends. This will require allowing the backends to hook into the cmd processing for SPC commands, so this renames sbc_ops to a more generic exec_cmd_ops.
