Subject: [PATCH v2 00/16] driver core: make more things const!
Date: Wed, 11 Jan 2023 12:30:02 +0100 [thread overview]
Message-ID: <20230111113018.459199-1-gregkh@linuxfoundation.org> (raw)
Here's an updated version of this original series:
https://lore.kernel.org/all/20221123122523.1332370-1-gregkh@linuxfoundation.org/
that has the goal of making more functions in the driver core take const
pointers as they do not actually modify anything. This work is an
outgrowth of some conversations I had with the Linux Rust developers
talking about the mutability of many of the driver model pointers.
A small subset of the original submission is now in 6.2-rc1 and this
series is an outgrown of the original submission in that many things are
now changed and a bit more explicit than before.
I can take all of these through the driver-core git tree as they depend
on each other. 0-day has been passing on this series for quite a while,
so all should be good unless some subsystem trees have added new busses
without me noticing.
Bonus for all of this work, the overall code size of the kernel actually
decreased a tiny bit:
126 files changed, 283 insertions(+), 309 deletions(-)
while adding a lot more type-safeness to the system.
Changes from v1:
- rebased on 6.2-rc1 and dropped accepted patches already in there.
- container_of_const() is now in 6.2-rc1 so use that in many
individual subsystems to make the follow-on changes in the driver
core more obvious.
- collected some Reviewed-by
- of_device_uevent_modalias was being "abused" by many different
subsystems in using it instead of a local bus function which played
havoc when enabling stricter type-checking. Move that out into a
new function for the busses that were doing this to make it more
obvious what they need here.
Greg Kroah-Hartman (16):
of: device: make of_device_uevent_modalias() take a const device *
i3c: move dev_to_i3cdev() to use container_of_const()
platform/surface: aggregator: move to_ssam_device() to use
container_of_const()
firewire: move fw_device() and fw_unit() to use container_of_const()
driver core: make struct device_type.uevent() take a const *
driver core: make struct device_type.devnode() take a const *
driver core: device_get_devnode() should take a const *
vio: move to_vio_dev() to use container_of_const()
platform/x86: wmi: move dev_to_wblock() and dev_to_wdev to use
container_of_const()
drivers: hv: move device_to_hv_device to use container_of_const()

drm/mipi-dsi: move to_mipi_dsi_device() to use container_of_const()
mcb: move to_mcb_device() to use container_of_const()
xen/xenbus: move to_xenbus_device() to use container_of_const()
driver core: make struct bus_type.uevent() take a const *
kobject: kset_uevent_ops: make uevent() callback take a const *
