Subject: [PATCH net-next v2 00/15] devlink: code split and structured instance walk
Date: Wed, 4 Jan 2023 20:05:16 -0800 [thread overview]
Message-ID: <20230105040531.353563-1-kuba@kernel.org> (raw)
Split devlink.c into a handful of files, trying to keep the "core"
code away from all the command-specific implementations.
The core code has been quite scattered until now. Going forward we can
consider using a source file per-subobject, I think that it's quite
beneficial to newcomers (based on relative ease with which folks
contribute to ethtool vs devlink). But this series doesn't split
everything out, yet - partially due to backporting concerns,
but mostly due to lack of time. Bulk of the netlink command
handling is left in a leftover.c file.
Introduce a context structure for dumps, and use it to store
the devlink instance ID of the last dumped devlink instance.
This means we don't have to restart the walk from 0 each time.
Finally - introduce a "structured walk". A centralized dump handler
in devlink/netlink.c which walks the devlink instances, deals with
refcounting/locking, simplifying the per-object implementations quite
a bit. Inspired by the ethtool code.
v2:
- various renames
- split patch 2
v1: https://lore.kernel.org/all/20230104041636.226398-1-kuba@kernel.org/
- re-route the locking fix via net
- rename basic.c -> leftover.c
RFC: https://lore.kernel.org/all/20221215020155.1619839-1-kuba@kernel.org/
Jakub Kicinski (15):
devlink: move code to a dedicated directory
devlink: rename devlink_netdevice_event ->
devlink_port_netdevice_event
devlink: split out core code
devlink: split out netlink code
netlink: add macro for checking dump ctx size
devlink: use an explicit structure for dump context
devlink: remove start variables from dumps
devlink: drop the filter argument from devlinks_xa_find_get
devlink: health: combine loops in dump
devlink: restart dump based on devlink instance ids (simple)
devlink: restart dump based on devlink instance ids (nested)
devlink: restart dump based on devlink instance ids (function)
devlink: uniformly take the devlink instance lock in the dump loop
devlink: add by-instance dump infra
devlink: convert remaining dumps to the by-instance scheme
