Subject: [Qemu-devel] [PATCH 0/5] qcow2: Discard freed clusters
Date: Thu, 13 Jun 2013 13:47:38 +0200 [thread overview]
Message-ID: <1371124063-12971-1-git-send-email-kwolf@redhat.com> (raw)
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.
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
