--- Comment #213 from Guenter Roeck (linux@...ck-us.net) ---
#210: I rather refrain from it. Messing up one of my systems is bad enough.

Note that the problem is still spurious; it may happen a mionute into the test 
(or even during boot), or after an hour.

I am now at a point where I still see the problem with almost all patches since
4.18.20 reverted; the only patch not reverted is the STAT_WRITE patch, because
it is difficult to revert due to context changes. I'll revert that manually for
the next round of tests. Here is the most recent log:

[ 2228.782567] EXT4-fs error (device sda1): ext4_iget:4795: inode #6317073:

... and so on.
