eventfs: Do not allow NULL parent to eventfs_start_creating()

Browse source

[ Upstream commit fc4561226f ]

The eventfs directory is dynamically created via the meta data supplied by
the existing trace events. All files and directories in eventfs has a
parent. Do not allow NULL to be passed into eventfs_start_creating() as
the parent because that should never happen. Warn if it does.
