  Eventfs bug fixes and clean ups:

- Use GFP_NOFS for allocations done under eventfs_mutex.
  The eventfs_mutex can be taken on file system reclaim, make sure
  that allocations done under that mutex do not trigger file system
  reclaim.

- Clean up code by moving the taking of inode_lock out of the helper
  functions and into where they are needed, and not use the
  parameter to know to take it or not. It must always be held but
  some callers of the helper function have it taken when they were
  called.

- Warn if the inode_lock is not held in the helper functions.

- Warn if eventfs_start_creating() is called without a parent.
  As eventfs is underneath tracefs, all files created will have
  a parent (the top one will have a tracefs parent).

Tracing update;

- Add Mathieu Desnoyers as an official reviewer of the tracing sub system.
