Good point on the symlink code we must be copying the null already.

There's another strange one I hit at mount time last week but forgot to
include.  It could be noise from earlier debugging runs of the patch that left
readonly pages setting around, but I think if I squint really it makes sense.

During mounts and remounts, ext4 will mess around with the flags on the journal
super.  I don't see exactly where the buffer is logged or prepared...most of
the callers of jbd2_journal_clear_features look like they need a bigger audit
to me.

Does anyone know the perf cost of forcing the page ro/rw?  I'm looking at
integrating it into a CONFIG_DEBUG_CSUMS for btrfs.  For any individual page it
shouldn't happen too often, but we'd be hammering on it pretty good during a
commit.
