From 5cd3167a5ebbbe49516f29e5dd16317ab6ff479a Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Mon, 11 Nov 2024 14:10:56 +0100 Subject: scsi: target: tcmu: Constify some structures 'struct nla_policy' and 'struct match_table_t' are not modified in this driver. Constifying these structures moves some data to a read-only section, so increase overall security, especially when the structure holds some function pointers, which is the case of struct nla_policy.
