[ovs-dev] [PATCH net-next 3/3] genetlink: remove linux/genetlink.h

2024-03-09 Thread Jakub Kicinski
genetlink.h is a shell of what used to be a combined uAPI
and kernel header over a decade ago. It has fewer than
10 lines of code. Merge it into net/genetlink.h.
In some ways it'd be better to keep the combined header
under linux/ but it would make looking through git history
harder.

[ovs-dev] [PATCH net-next 2/3] net: openvswitch: remove unnecessary linux/genetlink.h include

2024-03-09 Thread Jakub Kicinski
The only legit reason I could think of for net/genetlink.h
and linux/genetlink.h to be separate would be if one was
included by other headers and we wanted to keep it lightweight.
That is not the case, net/openvswitch/meter.h includes
linux/genetlink.h but for no apparent reason (for struct genl_family
perhaps? it's not necessary, types of externs do not need
to be known).
