[PATCH v9] virtio_blk: add discard and write zeroes support
Hi Daniel,
Other than crosvm, is there any version of qemu (e.g., repositories developed in
progress on github) where I can try with this feature?
Thank you very much!

[PATCH v3] virtio_blk: add DISCARD and WRIET ZEROES command support
Existing virtio-blk protocol doesn't have DISCARD/WRITE ZEROES
command support, this will impact the performance when using SSD
backend over file systems.
The idea here is using 16 Bytes payload as one descriptor for
DISCARD/WRITE ZEROES command, users can put several ranges into
one command, for the purpose to support such feature, two feature
flags

[PATCH v2] virtio-blk: add DISCARD support to virtio-blk driver
Currently virtio-blk driver does not provide discard feature flag, so the
filesystems which built on top of the block device will not send discard
command. This is okay for HDD backend, but it will impact the performance
for SSD backend.
Add a feature flag VIRTIO_BLK_F_DISCARD and command VIRTIO_BLK_T_DISCARD
to extend exist virtio-blk protocol, define 16 bytes discard descriptor
for each discard
