    Pull tracing fixes from Steven Rostedt:
     "While doing tests on tracing over the network, I found that the
      packets were getting corrupted.
    
      In the process I found three bugs.
    
      One was the culprit, but the other two scared me. After deeper
      investigation, they were not as major as I thought they were, due to a
      signed compared to an unsigned that prevented a negative number from
      doing actual harm.
    
      The two bigger bugs:
    
       - Mask the ring buffer data page length. There are data flags at the
         high bits of the length field. These were not cleared via the
         length function, and the length could return a negative number.
         (Although the number returned was unsigned, but was assigned to a
         signed number) Luckily, this value was compared to PAGE_SIZE which
         is unsigned and kept it from entering the path that could have
         caused damage.
    
       - Check the page usage before reusing the ring buffer reader page.
         TCP increments the page ref when passing the page off to the
         network. The page is passed back to the ring buffer for use on
         free. But the page could still be in use by the TCP stack.
    
      Minor bugs:
    
       - Related to the first bug. No need to clear out the unused ring
         buffer data before sending to user space. It is now done by the
         ring buffer code itself.
    
       - Reset pointers after free on error path. There were some cases in
         the error path that pointers were freed but not set to NULL, and
         could have them freed again, having a pointer freed twice"
