I "think" this is the suggested fix:

Ugh, this is just too ugly for words.

That's not a fix. That's a "hide the problem" patch.

Now, admittedly clearly the "hide the problem" code already existed,
and was just moved earlier, but I really think this whole "we're
calling __mark_inode_dirty() on an inode that isn't even *initialized*
yet" is a much deeper issue, and shouldn't have some hacky work-around
in __mark_inode_dirty() that just happens to make it work.

I don't mind that patch per se - moving the code is fine.

But I *do* mind the patch when the reason is to hide that wrong
ordering of operations.

Now, maybe a proper fix might be to say that new_inode_pseudo() should
always initialize i_state to I_DIRTY_ALL or something like that. The
comment already says that they cannot participate in writeback, so
maybe they should be disabled that way (ie a pseudo inode is always
dirty and marking it dirty does nothing).

And then you get rid of the noop_backing_dev_info entirely.

Or just make sure that noop_backing_dev_info is fully initialized
before it's used.

Because I think the real problem here is that things have a pointer to
an uninitialized backing_dev_info.

Hmm? Jan?

I don't see any real reason why that

    err = bdi_init(&noop_backing_dev_info);

couldn't just be done very early. Maybe as the first call in
driver_init(), before the whole devtmpfs_init() etc.

But I might be missing some dependency there.

I agree it is papering over the real problem. I consider that a stopgap
solution so that machines can boot until we find a cleaner solution.

Sadly it is not so simple. Firstly, new_inode_pseudo() gets used for all
inodes (through new_inode()), secondly, tmpfs allocates fully standard
inodes through new_inode() as any other filesystem. We could check
writeback capabilities of the sb->s_bdi in new_inode_pseudo() but that
would not work for inodes that will become block device inodes because
blockdev_superblock has noop_backing_dev_info so we'd have to specialcase
that. Overall it looks a bit hairy to my taste.

> And then you get rid of the noop_backing_dev_info entirely.

And this would be even more difficult because there are other places that
expect there's *some* bdi associated with each sb.

I fully agree with this. IMHO we need to initialize noop_backing_dev_info
earlier but early init is not exactly my comfort zone so I have to verify
whether various stuff in cgwb_bdi_init() is safe to call so early...

I've checked the dependencies and cgroups (which are the only non-trivial
dependency besides per-CPU infrastructure) are initialized early enough so
it should work fine. So let's try that.

noop_backing_dev_info is used by superblocks of various
pseudofilesystems such as kdevtmpfs. Initialize it before the
filesystems get mounted.

I spoke a bit too early. I see the following backtrace in some qemu arm
boot tests.

mainline kernel. v5.15.y.queue and later are affected. Reverting the patch
