[Qemu-devel] [PATCH v2 0/5] qcow2: Discard freed clusters |

This series adds options to make qcow2 discard freed clusters, in several
categories. By default, only freed clusters related to snapshots (i.e. mainly
snapshot deletion) are discarded.
v2:
- Removed leftover debug code
- Don't discard after COW (overwriting compressed clusters)
- Changed some commas into semicolons
Kevin Wolf (5):
Revert "block: Disable driver-specific options for 1.5"
qcow2: Add refcount update reason to all callers
qcow2: Options to enable discard for freed clusters
qcow2: Batch discards
block: Always enable discard on the protocol level
