23 interface to the file system, to when it completed. This spans everything:
24 block device I/O (disk I/O), file system CPU cycles, file system locks, run

64 A threshold of 0 will trace all operations. Warning: the output will be
65 verbose, as it will include all file system cache hits.
109 A -j option will print just the fields (parsable output, csv):
