Apologies for the delay; I've just returned from a long trip to Seattle
where I attended the Open Source Summit. After reviewing the bcachefs
CI testing results for v3, it appears that my patch has caused some
Kernel panic and soft lockup issues in bcachefs. However, I haven't
been able to reproduce these problems in my qemu testing environment,
so I'm unsure where I went wrong to cause these errors.
