  "message": "[PATCH] Keys: Use RCU to manage session keyring pointer\n\nThe attached patch uses RCU to manage the session keyring pointer in struct\nsignal_struct.  This means that searching need not disable interrupts and get\na the sighand spinlock to access this pointer.  Furthermore, by judicious use\nof rcu_read_(un)lock(), this patch also avoids the need to take and put\nrefcounts on the session keyring itself, thus saving on even more atomic ops.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
