All of the members of mlx5_cache_ent must be accessed while holding the spinlock, add the missing spinlock in the __cache_work_func(). Using cache->stopped and flush_workqueue() is an inherently racy way to shutdown self-scheduling work on a queue. Replace it with ent->disabled under lock, and always check disabled before queuing any new work. Use cancel_work_sync() to shutdown the queue. Use READ_ONCE/WRITE_ONCE for dev->last_add to manage concurrency as coherency is less important here. Split fill_delay from the bitfield. C bitfield updates are not atomic and this is just a mess. Use READ_ONCE/WRITE_ONCE, but this could also use test_bit()/set_bit().
