#     Pull ring-buffer fixes from Steven Rostedt:
#     
#      - Fix ref counter of buffers assigned at boot up
#     
#        A tracing instance can be created from the kernel command line. If it
#        maps to memory, it is considered permanent and should not be deleted,
#        or bad things can happen. If it is not mapped to memory, then the
#        user is fine to delete it via rmdir from the instances directory. But
#        the ref counts assumed 0 was free to remove and greater than zero was
#        not. But this was not the case. When an instance is created, it
#        should have the reference of 1, and if it should not be removed, it
#        must be greater than 1. The boot up code set normal instances with a
#        ref count of 0, which could get removed if something accessed it and
#        then released it. And memory mapped instances had a ref count of 1
#        which meant it could be deleted, and bad things happen. Keep normal
#        instances ref count as 1, and set memory mapped instances ref count
#        to 2.
#     
#      - Protect sub buffer size (order) updates from other modifications
#     
#        When a ring buffer is changing the size of its sub-buffers, no other
#        operations should be performed on the ring buffer. That includes
#        reading it. But the locking only grabbed the buffer->mutex that keeps
#        some operations from touching the ring buffer. It also must hold the
#        cpu_buffer->reader_lock as well when updates happen as other paths
#        use that to do some operations on the ring buffer.
