[PATCH] hfs{plus}: add deprecation warning

[PATCH] hfs{plus}: add deprecation warning

[Christian Brauner]

Both the hfs and hfsplus filesystem have been orphaned since at least
2014, i.e., over 10 years. It's time to remove them from the kernel as
they're exhibiting more and more issues and no one is stepping up to
fixing them.

Looks good. And I agree hopefully it sparks interest in the maintainership
because this is not completely useless filesystem:

Does this mean before or after the 2025 LTS kernel is released?  I would
say that we ought to let this circulate more widely among users, but
OTOH I guess no maintainer for a decade is really bad.

I would've tried before the LTS release...

which is a valid point. The removal of reiserfs and sysv has been pretty
surgically clean. So at least from my POV it should be simple enough to
revert the removal. But I'm not dealing with stable kernels so I have no
intuition about the pain involved.

Well you still could.  No better way to get an oft-ignored filesystem
back into maintenance by throwing down a deprecation notice. :)

It'll probably cause a lot of pain for the distributions that support
PPC Macs because that's the only fs that the OF knows how to read for
bootfiles.  For dual-boot Intel Macs, their EFI partition is usually
HFS+ and contains various system files (+ grub), but their EFI actually
can read FAT.  I have an old 2012 Mac Mini that runs exclusively Debian,
and a FAT32 ESP works just fine.

I contributed to HFS+ file system driver more than 10 years ago. And I was
completely discouraged because nobody maintained the HFS+ code base. But I would
prefer to see the HFS+ in kernel tree instead of complete removal. As far as I
can see, we are still receiving some patches for HFS/HFS+ code base. Nowadays, I
am mostly busy with CephFS and SSDFS file systems. But if we need more
systematic activity on HFS/HFS+, then I can find some time for HFS/HFS+ testing,
bug fix, and pathes review. I am not sure that I would have enough time for HFS+
active development. But is it really that nobody would like to be the maintainer
of HFS/HFS+? Have we asked the contributors and reviewers of HFS/HFS+?

Thanks,
Slava.

If you're willing to step up as a maintainer, I would be happy to assist you by
testing and reviewing patches. I have PowerMacs available for testing and it's
also possible to just install Debian's 32-bit and 64-bit PowerPC on an emulated
PowerMac on QEMU using the "mac99" machine types to test booting from an HFS/HFS+
partition [1].

I am Debian's primary maintainer of these PowerPC ports in Debian (not to be confused
with the little-endian PowerPC port) and I can also easily build various test images
if needed.

Please let me know if you're interested in working together on the HFS/HFS+ driver.

Adrian

Sounds good! Yes, I am interested in working together on the HFS/HFS+ driver. :)
And, yes, I can consider to be the maintainer of HFS/HFS+ driver. We can
maintain the HFS/HFS+ driver together because two maintainers are better than
one. Especially, if there is the practical need of having HFS/HFS+ driver in
Linux kernel.

Thanks,
Slava.

OK, then let's do this together! While I'm already a kernel maintainer (for arch/sh),
I wouldn't call myself an expert on filesystems and I feel way more comfortable working
on this when there is a second person around with experience with hacking on filesystems.

Can you send a patch to update MAINTAINERS?

My mail entry would be:

Do you mind if there is one more person?

I used to maintain Allwinner SoC cpufreq and thermal drivers and have some work experience
in the F2FS file system.

I have a MacBook laptop and can help verify and maintain patches if needed.

Sounds good! I believe that three persons could be better for patches
verification and discussions. I have no objections. :)

Absolutely not. The more people we have, the better. I suggest that Slava maintains
the tree and we're working with him to review and test patches since we both have
the hardware at hands.

I might be willing to take over maintainership as we definitely need this
driver to stay for Debian Ports as otherwise we won't be able to boot
PowerMacs using GRUB.

Developers on the grub-devel mailing list might be interested in this
discussion as well as GRUB won't be usable anymore on PowerMacs with
HFS/HFS+ being removed from the kernel.
