[v2] block/nvme: add support for write zeros and discard

[Qemu-devel] [PATCH v2 0/2] block/nvme: add support for write zeros and discard

Posted by Maxim Levitsky 4 years, 7 months ago

This is the second part of the patches I prepared
for this driver back when I worked on mdev-nvme.

V2: addressed review feedback, no major changes

Best regards,

Thanks, fixed the indentation in nvme.h in patch 1, and applied to my
block branch:

https://git.xanclic.moe/XanClic/qemu/commits/branch/block

For the record, I don’t think !!x has benefits over x != 0 and I
personally prefer bool y = x over any of it. O:-)

Well, that's even better :) For me, it's about making booleans obvious
as booleans and that's all.
