--- Comment #1 from Eric Sandeen (sandeen@sandeen.net) ---
Hi, this is the upstream kernel bug tracker, and 3.10.0-862.el7.x86_64 is not
an upstream kernel.  This is not the appropriate bug tracker for distribution
kernels.

Also, you've not provided any reproducer steps, just a screenshot of du & ls
which shows no problem.

There is no expectation that du should match ls.  One reflects the maximum
offset in a file, the other reflects the amount of space allocated to the file.
 They are two different quantities.  Observe:

# fallocate -l 161m output.out
# truncate --size 18g output.out

# du -h output.out
161M    output.out

# ls -lh output.out
-rw-r--r--. 1 root root 18G Dec 12 10:30 output.out
