- kprobes: Use a dedicated kernel thread to optimize the kprobes instead of using workqueue thread. Since the kprobe optimizer waits a long time for synchronize_rcu_task(), it can block other workers in the same queue if it uses a workqueue. - kprobe-events: Returns immediately if no new probe events are specified on the kernel command line at boot time. This shorten the kernel boot time. - kprobes: When a kprobe is fully removed from the kernel code, retry optimizing another kprobe which is blocked by that kprobe. -----BEGIN PGP SIGNATURE----- iQFPBAABCgA5FiEEh7BulGwFlgAOi5DV2/sHvwUrPxsFAmmPtX4bHG1hc2FtaS5o aXJhbWF0c3VAZ21haWwuY29tAAoJENv7B78FKz8bgoUH/0oZ9/c+wkn9AKxFlOAw AIbtTfKiQHXPirhamYuEbJJWTUH2O/Wr0SQrIkbwJzToou5CRTuT5UQBpmOk2GKZ uZ5bO63nOMn/1ECbDpc+lFGV5J4Dn5Pw2GFjUTR6EPwms+CN/d6f2LlvuAVfJX7Y klL2X9/QLwV5QT8La5zNEka2zBfrZlZ9a5DGoLtgdwX2zosuef9aDnisS2jkLenH wugZLryx0Qvlj9DXimP7oVZpYDHr0hZEI3CNQPge0gMQDj1XajGawYfkhrfaeFMX 4eXjFCN+NQG6fBUpDugcOThOypWmjlJhoYxxROJu0eFcLQjsuWjp6jLixI9Nr7P+ tQk= =syAj -----END PGP SIGNATURE----- Merge tag 'probes-v7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull kprobes updates from Masami Hiramatsu: - Use a dedicated kernel thread to optimize the kprobes instead of using workqueue thread.
