    Subject[PATCH 3.18 27/56] Smack: Mark inode instant in smack_task_to_inode
    Date
    3.18-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Casey Schaufler <casey@schaufler-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.
