Well, stuff like fs/reiserfs, fs/udf, fs/isofs, or fs/quota are also parts
of filesystem space but good luck with finding reviewers for those. 99% of
patches I sent in last 10 years were just met with silence (usually there's
0-1 developer interested in that code) so I just push them to have the bug
fixed... I don't feel that as a big problem since the code is reasonably
simple, can be tested, change rate is very low. I just wanted to give that
as an example that above rule does not work for everybody.

For larger filesystems I agree 'at least one reviewer' is a good rule. XFS
is known for this, I believe btrfs pretty much enforces it as well, Ted is
not enforcing this rule for ext4 AFAIK and often it is up to him to review
patches but larger / more complex stuff generally does get reviewed. So
IMO ext4 could use some improvement but I'll leave up to Ted to decide
what's better for ext4.
