Pull tracing fixes from Steven Rostedt:

 - Fix the buffer_percent accounting as it is dependent on three
   variables:

     1) pages_read - number of subbuffers read
     2) pages_lost - number of subbuffers lost due to overwrite
     3) pages_touched - number of pages that a writer entered

   These three counters only increment, and to know how many active
   pages there are on the buffer at any given time, the pages_read and
   pages_lost are subtracted from pages_touched.

   But the pages touched was incremented whenever any writer went to the
   next subbuffer even if it wasn't the only one, so it was incremented
   more than it should be causing the counter for how many subbuffers
   currently have content incorrect, which caused the buffer_percent
   that holds waiters until the ring buffer is filled to a given
   percentage to wake up early.

 - Fix warning of unused functions when PERF_EVENTS is not configured in

 - Replace bad tab with space in Kconfig for FTRACE_RECORD_RECURSION_SIZE

 - Fix to some kerneldoc function comments in eventfs code.
