Subject: [PATCH net-next v5 0/4] net: devlink: return the driver name in devlink_nl_info_fill
The driver name is available in device_driver::name. Right now,
drivers still have to report this piece of information themselves in
their devlink_ops::info_get callback function.
The goal of this series is to have the devlink core to report this
information instead of the drivers.
The first patch fulfills the actual goal of this series: modify
devlink core to report the driver name and clean-up all drivers. Both
have to be done in an atomic change to avoid attribute duplication.
The second patch removes the devlink_info_driver_name_put() function
to prevent future drivers from reporting the driver name themselves.
The third patch allows the core to call devlink_nl_info_fill() even if
the devlink_ops::info_get() callback is NULL. This leads to the fourth
and final patch which cleans up the drivers which have an empty
info_get().
---
* Changelog *
v4 -> v5
* [PATCH 1/4] add Tested-by: Ido Schimmel tag.
* split patch 3/3 in two patches.
v3 -> v4
* Ido pointed out that the mlxsw did not need to be fixed:
https://lore.kernel.org/netdev/Y4ONgD4dAj8yU2%2F+@shredder/
Remove the first two patches from the series.
v2 -> v3
* [PATCH 3/5] remove the call to devlink_info_driver_name_put() in
mlxsw driver as well (this was missing in v2, making the build
fail... sorry for the noise).
* add additional people in CC as pointed by netdev patchwork CI:
https://patchwork.kernel.org/project/netdevbpf/list/?series=699451
* use the "Link:" prefix before URL to silence checkpatch's line
length warning.
RFC v1 -> v2
* drop the RFC tag
* big rework following the discussion on RFC:
https://lore.kernel.org/netdev/20221122154934.13937-1-mailhol.vincent@wanadoo.fr/
Went from one patch to a series of five patches:
* drop the idea to report the USB serial number following Greg's
comment:
https://lore.kernel.org/linux-usb/Y3+VfNdt%2FK7UtRcw@kroah.com/
