Pull tracing fixes from Steven Rostedt:

 - Fix readers that are blocked on the ring buffer when buffer_percent
   is 100%. They are supposed to wake up when the buffer is full, but
   because the sub-buffer that the writer is on is never considered
   "dirty" in the calculation, dirty pages will never equal nr_pages.
   Add +1 to the dirty count in order to count for the sub-buffer that
   the writer is on.

 - When a reader is blocked on the "snapshot_raw" file, it is to be
   woken up when a snapshot is done and be able to read the snapshot
   buffer. But because the snapshot swaps the buffers (the main one with
   the snapshot one), and the snapshot reader is waiting on the old
   snapshot buffer, it was not woken up (because it is now on the main
   buffer after the swap). Worse yet, when it reads the buffer after a
   snapshot, it's not reading the snapshot buffer, it's reading the live
   active main buffer.

   Fix this by forcing a wakeup of all readers on the snapshot buffer
   when a new snapshot happens, and then update the buffer that the
   reader is reading to be back on the snapshot buffer.

 - Fix the modification of the direct_function hash. There was a race
   when new functions were added to the direct_function hash as when it
   moved function entries from the old hash to the new one, a direct
   function trace could be hit and not see its entry.

   This is fixed by allocating the new hash, copy all the old entries
   onto it as well as the new entries, and then use rcu_assign_pointer()
   to update the new direct_function hash with it.

   This also fixes a memory leak in that code.

 - Fix eventfs ownership
