--- Comment #1 from Eric Sandeen ---
If you really want that option (which, btw, had been simply ignored on =
a
remount, prior to this change) you can add it to the rootflags=3D kerne=
l
parameter.
But also:

[PATCH 2/2, RFC] ext4: ignore journal checksum on remount; don't fail
As of v3.18, ext4 started rejecting a remount which changes the
journal_checksum option.
Prior to that, it was simply ignored; the problem here is that
if someone has this in their fstab for the root fs, now the box
fails to boot properly, because remount of root with the new options
will fail, and the box proceeds with a readonly root.
I think it is a little nicer behavior to accept the option, but
warn that it's being ignored, rather than failing the mount,
but that might be a subjective matter...
