Subject: [PATCH 4.14 075/217] Smack: Mark inode instant in smack_task_to_inode
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Casey Schaufler <casey@...aufler-ca.com>
[ Upstream commit 7b4e88434c4e7982fb053c49657e1c8bbb8692d9 ]
Smack: Mark inode instant in smack_task_to_inode
/proc clean-up in commit 1bbc55131e59bd099fdc568d3aa0b42634dbd188
resulted in smack_task_to_inode() being called before smack_d_instantiate.
This resulted in the smk_inode value being ignored, even while present
for files in /proc/self. Marking the inode as instant here fixes that.
