[PATCH v1 0/8] Correct inject's handling of pipe files on disk

[Ian Rogers]

Perf inject tried to repipe the header, but this isn't possible if the
input is a pipe and the output a file, as the attributes are events in
pipe mode. Add an ability to write the attributes after the data so
writing the header doesn't need a possibly too large or small region
reserved for the attributes. Add testing for the case of a pipe mode
file on disk, add checks that the perf file's header isn't obviously
corrupt by having the header, data or attribute sections overlap. Add
more comments.

Ian Rogers (8):
  perf report: Name events in stats for pipe mode
  perf session: Document struct and constify auxtrace
  perf header: Add kerneldoc to perf_file_header
  perf header: Fail read if header sections overlap
  perf header: Allow attributes to be written after data
  perf inject: Overhaul handling of pipe files
  perf header: Remove repipe option
  perf test: Additional pipe tests with pipe output written to a file
