Well, yes, there are certainly things in the affs code that can cause
unexpected behavior. But that wasn't my point. My point was that the
purpose for what people are using the affs driver in the kernel, it's
doing its job perfectly fine.

The standard use case is either to run Debian m68k on an Amiga and
access the Amiga partitions through Linux for simple file transfers
between the two operating systems, e.g. copying a new kernel plus
newly generated initrd to the affs boot partition of AmigaOS.

Or, just reading data off an old Amiga harddisk or floppy disk by
either attaching the disk to the Linux machine directly or reading
the contents of a floppy disk with an advanced floppy disk controller
like the Catweasel or KryoFlux.

For both cases, I haven't run into any issues with the affs driver
and I also haven't heard of complaints from anyone in communities
like EAB Amiga, amiga.org, a1k.org etc. That doesn't mean that people
haven't run into issues, of course. I'm just saying I haven't heard
of any.

Not that I know of.

PS: Even Matthew Garrett seems to be a Linux/m68k fan:
