[Qemu-devel] [PATCH v2] qmp-commands.hx: Update the supported 'transacti


From: Kashyap Chamarthy
Subject: [Qemu-devel] [PATCH v2] qmp-commands.hx: Update the supported 'transaction' operations
Date: Fri, 24 Apr 2015 10:32:47 +0200

Although the canonical source of reference for QMP commands is
qapi-schema.json, for consistency's sake, update qmp-commands.hx to
state the list of supported transactionable operations, namely:

    drive-backup
    blockdev-backup
    blockdev-snapshot-internal-sync
    abort
    block-dirty-bitmap-add
    block-dirty-bitmap-clear

NB: The 'block-dirty-bitmap-add' and 'block-dirty-bitmap-clear' commands
will be available once the in-review "transactionless incremental
backup" patch series[1] is merged upstream.
