Comment (by jmroot):

 OK. Given the way the kernel code is structured with the VFS and UBC at
 higher levels, it seems unlikely that the bug is in the actual APFS layer.
 It does seem likely that it could have been introduced when adding generic
 support in higher layers for features that APFS implements. But you'd
 probably be hard pressed to find anyone using any other filesystem for the
 MacPorts build dir on these OS versions, and we've seen few enough
 instances of the problem on APFS.

 Given that, for better or worse, this ticket is now one of the few sources
 of information on the issue, it's probably better to use a more generic
 term to avoid misleading anyone.
