From 03a68b44faff1b3eef5424952044747c9c555f0e Mon Sep 17 00:00:00 2001 From: Andy Grover Date: Thu, 25 Feb 2016 15:14:32 -0800 Subject: target: Remove enum transport_lunflags_table se_dev_entry.lun_flags and se_lun.lun_access are only used for keeping track of read-write vs. read-only state. Since this is an either/or thing we can represent it as bool, and remove the unneeded enum transport_lunflags_table, which is left over from when there were more flags. Change code that uses this enum to just use true/false, and make it clear through variable and param names that true means read-only, false means read-write.
