He literally answers this criticism. ZFS is not userland so kernel developers are free to break it, just like they can break ext4 and do, and then they fix them. The problem with ZFS is that they &lt;i&gt;can&amp;#x27;t&lt;/i&gt; fix it because it&amp;#x27;s not part of linux. It&amp;#x27;s a 3rd party kernel module. So your entire comment reads like a misunderstanding of the situation.</text><parent_chain><item><author>tw04</author><text>That&amp;#x27;s a great theory, but Linus picks and chooses when to decide it&amp;#x27;s outrageous to make changes that break userland tools based on his personal preferences.

If he decides to break interfaces, I don&amp;#x27;t know that anyone can stop him.  It is a downside to the BDFL model.&lt;p&gt;Edit: Breaking ZFS is not a great example — as sibling comment points out, that is a kernel module using kernel-internal APIs, not userspace syscall ABI.  The Linux kernel notoriously considers all kernel interfaces unstable.  GregKH has in the past characterized this as a feature, not a bug.</text><parent_chain><item><author>tw04</author><text>That&amp;#x27;s a great theory, but Linus picks and chooses when to decide it&amp;#x27;s outrageous to make changes that break userland tools based on his personal preferences.
