[libvirt] [PATCH 0/5] Add support for fine grained discard control of qemu
* The 'discard_granularity' property is available to 'scsi-hd',
'virtio-blk' and 'ide-*'.
It impacts the 'Optimal Unmap Granularity' field in the block limits VPD page:
Optimal Unmap Granularity = discard granularity / logical block size
* The 'max_unmap_size' property is available to 'scsi-hd' and
'scsi-block'.
It impacts the 'Maximum unmap LBA count' field in the block limits VPD page:
Maximum unmap LBA count = max unmap size / logical block size
Lin Ma (5):
conf: Add support for discard granularity
qemu: Add Support for discard granularity
conf: Add support for unmap limit
qemu: caps: Add max_unmap_size property of scsi-disk
qemu: Add support for max_unmap_size property of scsi-disk
