From: Jiri Pirko <jiri@mellanox.com>
Now, the memory allocation in prepare/commit state is done separatelly
in each driver (rocker). Introduce the similar mechanism in generic
switchdev code, in form of queue. That can be used not only for memory
allocations, but also for different items. Commit/abort item destruction
is handled as well.

v1-v2:
- added comment blocks to exported functions as suggested by Scott
- made switchdev_trans_init and switchdev_trans_items_destroy static
- added documentation for this to switchdev.txt as suggested by Scott

+Transaction item queue
+^^^^^^^^^^^^^^^^^^^^^^
+
+For switchdev ops attr_set and obj_add, there is a 2 phase transaction model
+used. First phase is to "prepare" anything needed, including various checks,
+memory allocation, etc. The goal is to handle the stuff that is not unlikely
+to fail here. The second phase is to "commit" the actual changes.
+
+Switchdev provides an inftrastructure for sharing items (for example memory
+allocations) between the two phases.
+
+The object created by a driver in "prepare" phase and it is queued up by:
+switchdev_trans_item_enqueue()
+During the "commit" phase, the driver gets the object by:
+switchdev_trans_item_dequeue()
+
+If a transaction is aborted during "prepare" phase, switchdev code will handle
+cleanup of the queued-up objects.

Before this patchset, rocker would BUG_ON that the list was empty
after commit. This was really helpful in finding bugs in the driver
as it meant the commit and prepare phases didn't follow the same code
path. (Everything the driver queued in prepare was dequeued in
commit, so the list should be empty after commit).
Should this last switchdev_trans_items_destroy(&trans) be replaced with:
BUG_ON(!list_empty(&trans.item_list));

Sounds reasonable. Will change this.

Before it disappears completely, move transaction phase enum under
transaction structure and make attr/obj structures a bit cleaner.

There will be needed to have switchdev_trans available down in the call
chain, so propagate it instead of trans phase enum. This enum will be
removed anyway. Also, use prepare/commit phase check helpers to get
information about current phase of transaction.
