[PATCH Libvirt 1/3] qemu_capabilities: Introduce virtio-blk DISCARD and WRITE_ZEROES capabilities

~hyman hyman at git.sr.ht
Sun Jul 16 13:41:44 UTC 2023 

From: Hyman Huang(黄勇) <yong.huang at smartx.com>

DISCARD and WRITE_ZEROES commands has been implemented in virtio-blk
protocol since qemu >= 4.2.0.
Introduce QEMU_CAPS_VIRTIO_BLK_DISCARD and QEMU_CAPS_VIRTIO_BLK_WRITE_ZEROES
capability definitions.
