Hello,
We're running Linux kernel 4.14.x and our systems occasionally suffer a
bug which is already fixed:
https://github.com/torvalds/linux/commit/53cf978457325d8fb2cdecd7981b31a8229e446e
This bugfix hasn't been ported to Linux kernels 4.14 or 4.19. The patch
applies cleanly. The two files "fs/jbd2/checkpoint.c" and
"fs/jbd2/journal.c" seem pretty identical in the affected sections
compared to kernel 5.4 where we have this bugfix already applied.
Is it on purpose that this bugfix hasn't been ported to 4.14? Is it safe
that we backport it manually in our kernel 4.14 builds? Or is the "ext4"
system in 4.14 and 5.4 fundamentally different and this would lead to
data loss or other problems?
Thank you.
Best regards.
