H A Dapparmorfs.cdiff f51dcd0f621caac5380ce90fbbeafc32ce4517ae Wed Apr 10 13:04:34 CDT 2019 Al Viro <viro@zeniv.linux.org.uk> apparmorfs: fix use-after-free on symlink traversal

symlink body shouldn't be freed without an RCU delay. Switch apparmorfs
to ->destroy_inode() and use of call_rcu(); free both the inode and symlink
body in the callback.
