From 20a2aa47097aae7016209c4dbe392b3b25e0d883 Mon Sep 17 00:00:00 2001 From: Khadija Kamran Date: Wed, 23 Aug 2023 14:01:28 +0500 Subject: lsm: constify 'sb' parameter in security_sb_kern_mount() The "sb_kern_mount" hook has implementation registered in SELinux. Looking at the function implementation we observe that the "sb" parameter is not changing. Mark the "sb" parameter of LSM hook security_sb_kern_mount() as "const" since it will not be changing in the LSM hook.
