Hi all,
I recently noticed that on my test VMs with the Qemu NVMe emulations I
see a zero max_setors_kb limit in sysfs. It turns out Qemu advertises
a one-LBA optimal write size, which is a bit silly.
This series handles this odd case properly both in the block layer and
the nvme driver as a sort of defense in depth.
