From 869ab90f0ae0002ce6e9d3a5c75156ae8de48ffc Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Fri, 24 Mar 2017 18:03:48 -0700 Subject: block: constify struct blk_integrity_profile blk_integrity_profile's are never modified, so mark them 'const' so that they are placed in .rodata and benefit from memory protection.
