At least it is special-purpose "read only" filesystem currently shipping
on a few million phones, so the fall-out isn't a big deal :)
Also, the erofs developers have been asking for reviews for a very long
time and only now got them. Which goes back to the issue of vfs reviews
we all discussed last week (see below).

Those developers are still yet to be found, we only got a "drop" of the
samsung code _after_ this code was merged, from non-samsung people. No
samsung developers have said they would actually help with any of this
work, and when asked what differed from the in-tree stuff, I got a list,
but no specifics. I'll be working through that list over the next month
to resolve those issues.
Also the fat16/32 code is disabled, so that shouldn't be a problem for
Again, this is a special-purpose filesystem that will be under heavy
development for a while. There was no common out-of-tree place that
everyone could actually work on this, just inumerable forks on github,
my own included. Now we have that common place for this all to be
worked on, and also there is a very good legal benefit for this to be
in-tree, which always is a nice win.
To get back to the meta-problem here, we need a common "vfs/filesystem"
tree somewhere with reviewers. I'm glad to set up the tree and handle
patches, but I am not a vfs expert by any means (I only understand the
virtual half, not the backing half), so I can't be the only one to do
reviews. Do you know of anyone that we can drag in as reviewers to help
make it easier for new filesystems to get reviews as well as existing
ones to have their patches collected and forwarded on to Linus at the
