This serial will package backing chain snapshot code as one case, to make it
possible adding more operations later.
v2:
Address Kevin's comments:
Use the same prototype prepare, commit, rollback model in original code,
commit should never fail.
v3:
Address Stefan's comments:
3/5, 4/5: remove *action parameter since later only BlkTransactionStates* is
needed.
5/5: embbed BlkTransactionStates in ExternalSnapshotStates, *opaque is
removed, related call back function format change for external snapshot.
Address Kevin's comments:
removed all indention in commit message.
1/5: return void for prepare() function, *errp plays the role as error
checker.
5/5: mark *commit callback must exist, *rollback callback can be NULL. Align
"callback =" in "const BdrvActionOps external_snapshot_ops" to the same colum.
Address Eric's comments:
1/5: better commit message.
5/5: better commit message and comments in code that only one of rollback()
or commit() will be called.
v4:
5/5: document clean() callback will always be called if it present, declare
static for global variable "actions", use array plus .instance_size to remove
"switch" checking code according to caller input.
Wenchao Xia (5):
1 block: package preparation code in qmp_transaction()
2 block: move input parsing code in qmp_transaction()
3 block: package committing code in qmp_transaction()
4 block: package rollback code in qmp_transaction()
5 block: make all steps in qmp_transaction() as callback
