Description

My ceph version is 12.2.12
1、I create a rbd image, rbd info is:
  1. rbd info test_perf/gyt_export
    rbd image 'gyt_export':
    size 1GiB in 256 objects
    order 22 (4MiB objects)
    block_name_prefix: rbd_data.f89d5a6b8b4567
    format: 2
    features: layering, striping, exclusive-lock, object-map, fast-diff, deep-flatten
    flags:
    create_timestamp: Tue Dec 1 19:30:49 2020
    stripe unit: 128KiB
    stripe count: 16

2、write 1G date to this rbd image

3、# rbd export-diff gyt_export gyt_exported 2>export_stderr

The export_stderr file have a lot of repeat rate of progress,
if these date input to pipe, it is possible cause pipe_wait.
