[PATCH 0/2] block: propagate discard alignment from format drivers to the guest

2020-06-11 Thread Denis V. Lunev
Nowaday SCSI drivers in guests are able to align UNMAP requests before sending to the device. Right now QEMU provides an ability to set this via "discard_granularity" property of the block device which could be used by management layer. Though, in particular, from the point of QEMU, there is
