[Qemu-devel] [PATCH RFC 0/2] virtio-blk: add DISCARD and WRITE ZEROES features

Posted by Stefano Garzarella 6 years, 9 months ago

This series adds the support of DISCARD and WRITE ZEROES commands
and extends the virtio-blk-test to test WRITE_ZEROES command when
the feature is enabled.

RFC because I'm not sure if the "case" conditions that I used in
virtio-blk.c is clean enough.

This series requires the new virtio headers from linux v5.0-rc1
already imported by Paolo:

Based-on: <20190104082731.24967-1-pbonzini@redhat.com>

Thanks,
