2021-09-02ceph: reconnect to the export targets on new mdsmapsXiubo Li
In the case where the export MDS has crashed just after the EImportStart journal is flushed, a standby MDS takes over for it and when replaying the EImportStart journal the MDS will wait the client to reconnect. That may never happen because the client may not have registered or opened the sessions yet. When receiving a new map, ensure we reconnect to valid export targets as well if their sessions don't exist yet.

2021-09-02ceph: cancel delayed work instead of flushing on mdsc teardownJeff Layton
The first thing metric_delayed_work does is check mdsc->stopping, and then return immediately if it's set. That's good since we would have already torn down the metric structures at this point, otherwise, but there is no locking around mdsc->stopping. It's possible that the ceph_metric_destroy call could race with the delayed_work, in which case we could end up with the delayed_work accessing destroyed percpu variables. At this point in the mdsc teardown, the "stopping" flag has already been set, so there's no benefit to flushing the work. Move the work cancellation in ceph_metric_destroy ahead of the percpu variable destruction, and eliminate the flush_delayed_work call in ceph_mdsc_destroy.

2021-09-02ceph: flush the mdlog before waiting on unsafe reqsXiubo Li
For the client requests who will have unsafe and safe replies from MDS daemons, in the MDS side the MDS daemons won't flush the mdlog (journal log) immediatelly, because they think it's unnecessary. That's true for most cases but not all, likes the fsync request. The fsync will wait until all the unsafe replied requests to be safely replied. Normally if there have multiple threads or clients are running, the whole mdlog in MDS daemons could be flushed in time if any request will trigger the mdlog submit thread. So usually we won't experience the normal operations will stuck for a long time. But in case there has only one client with only thread is running, the stuck phenomenon maybe obvious and the worst case it must wait at most 5 seconds to wait the mdlog to be flushed by the MDS's tick thread periodically. This patch will trigger to flush the mdlog in the relevant and auth MDSes to which the in-flight requests are sent just before waiting the unsafe requests to finish.

No need to do the full VPID based task lookup and validation of the top waiter when the user space futex was acquired on it's behalf during the requeue_pi operation.

2021-09-02futex: Prevent inconsistent state and exit raceThomas Gleixner
The recent rework of the requeue PI code introduced a possibility for going back to user space in inconsistent state: CPU 0 CPU 1 requeue_futex() if (lock_pifutex_user()) { dequeue_waiter(); wake_waiter(task); sched_in(task); return_from_futex_syscall(); ---> Inconsistent state because PI state is not established It becomes worse if the woken up task immediately exits: sys_exit(); attach_pistate(vpid); <--- FAIL Attach the pi state before dequeuing and waking the waiter. If the waiter gets a spurious wakeup before the dequeue operation it will wait in futex_requeue_pi_wakeup_sync() and therefore cannot return and exit.
