| Subject: Smack: Mark inode instant in smack_task_to_inode |
| |
| 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. |
