The test mostly focus on testing various corner cases. The tests take a long time to run, so for the common.run runfile we randomly select a hundred tests. To run all the bclone tests, bclone.run runfile should be used. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Pawel Jakub Dawidek <pawel@dawidek.net> Closes #15631
