Description

In some test programs under lustre/tests directory, fprintf(stderr) does not print tailing newspace, which causes confusion in the log. The following is an example:

du: cannot access '/mnt/lustre/f71d.sanityn': No such file or directory
file size: 
cannot open /mnt/lustre/f71d.sanityn for reading, error 2 sanityn test_71d: @@@@@@ FAIL: checkfiemap failed 
^^^^^fprintf(sderr) in checkfiemap.c ^^^^^^^^^^^^^^^^^^^|^^^^^ error "checkfiemap failed" ^^^
  Trace dump:
