  i'm fairly familiar with the layout of the kernel source and i can
assure you that that ext4.h file above doesn't represent the layout of
the ext4 filesystem.  it's under the include/trace/events directory so
it's clearly related to system tracing, not filesystem structure.

  let's just put all this on hold until i have the time this evening
to do a more thorough search.
