David Howells 8589b4e00e [PATCH] Keys: Use RCU to manage session keyring pointer ... The attached patch uses RCU to manage the session keyring pointer in struct signal_struct. This means that searching need not disable interrupts and get a the sighand spinlock to access this pointer. Furthermore, by judicious use of rcu_read_(un)lock(), this patch also avoids the need to take and put refcounts on the session keyring itself, thus saving on even more atomic ops.
