This was done entirely with mindless brute force, using git grep -l '\

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

devlink: introduce a helper for netlink multicast send

2023-12-19T14:31:40+00:00

Introduce a helper devlink_nl_notify_send() so each object notification function does not have to call genlmsg_multicast_netns() with the same arguments. Signed-off-by: Jiri Pirko Signed-off-by: Paolo Abeni

devlink: send notifications only if there are listeners

2023-12-19T14:31:40+00:00

Introduce devlink_nl_notify_need() helper and using it to check at the beginning of notification functions to avoid overhead of composing notification messages in case nobody listens. Signed-off-by: Jiri Pirko Signed-off-by: Paolo Abeni

devlink: introduce __devl_is_registered() helper and use it instead of xa_get_mark()

2023-12-19T14:31:40+00:00

Introduce __devl_is_registered() which does not assert on devlink instance lock and use it in notifications which may be called without devlink instance lock held. Signed-off-by: Jiri Pirko Signed-off-by: Paolo Abeni

devlink: rename netlink callback to be aligned with the generated ones

2023-10-23T23:12:47+00:00

All remaining doit and dumpit netlink callback functions are going to be used by generated split ops. They expect certain name format. Rename the callback to be aligned with generated names.

devlink: convert linecard nested devlink to new rel infrastructure

2023-09-17T13:01:47+00:00

Benefit from the newly introduced rel infrastructure, treat the linecard nested devlink instances in the same way as port function instances. Convert the code to use the rel infrastructure. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

devlink: extend devlink_nl_put_nested_handle() with attrtype arg

2023-09-17T13:01:46+00:00

As the next patch is going to call this helper with need to fill another type of nested attribute, pass it over function arg. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

devlink: move devlink_nl_put_nested_handle() into netlink.c

2023-09-17T13:01:46+00:00

As the next patch is going to call this helper out of the linecard.c, move to netlink.c. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

devlink: put netnsid to nested handle

2023-09-17T13:01:46+00:00

If netns of devlink instance and nested devlink instance differs, put netnsid attr to indicate that. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller
