Some scripts relies on output order of do_read(), let's append the
new logs to keep forward compatibility.
e.g.
f2fs_io read 128 0 $((2*1024)) buffered 1 0 /mnt/f2fs/file
Before:
Read 1073741824 bytes IO time = 153715 us mlock time = 0 us, BW = 6985 MB/s
print 0 bytes:
00000000 :
After:
Read 1073741824 bytes total_time = 155166 us, BW = 6920 MB/s, IO time = 155166
us, mlock time = 0 us, print 0 bytes:
00000000 :
Fixes: 615036f ("f2fs_io: calculate IO bandwidth vs. mlock latency")
