This series includes several patches related to accessing
trace_event_file from a file struct. The first two patches are fixes for
edge cases, the remaining patches are minor cleanups.

Changes since v2 [1]:
* Split the first patch related to hist event files into two: one that
  corrects the trace_event_file access method and another that ensures
  pollers are woken up when the watched event is removed.

Changes since v1 [2]:
* Fix a compilation error when CONFIG_HIST_TRIGGERS is not set.
* Drop a patch that references the trace_event_file data in
  event_file_data() and keep the simpler implementation of storing the
  id in i_private.
* Inline event_file_data() into event_id_read() to enable adding
  additional checks to the former.
