Hi Kunwu Chan,

I think this is more of a cleanup than a fix,
so it should probably be targeted at 'nf-next' rather than 'net'.

Thanks, I'm confused about when to use "nf-next" or "net" or "net-next".
"nf-next" means fixing errors for linux-next.git and linux-stable.git, while
"nf" or "next" just means linux-next.git?


Hi Kunwu,

nf is for fixes for Netfilter (which includes IPVS). The target tree is nf.git
nf-next is for non-fixes for Netfilter. The target tree if nf-next.git

net is for fixes for Networking code, which does not have a more specific
tree (as is the case for Netfilter). The target tree is net.git.
Liikewise, net-next is for non-fixes for Networking code.
The target tree is net-next.git


Hi Simon,

Thank you very much for your detailed guidance.
In the future, I will carefully follow the rules you introduced to set 
the appropriate subject for the patch.




The MAINTAINERS file, and get_maintainers.pl script are useful here.

nf is merged into net on request from the Netfilter maintainers,
this is it's path to released kernels.
Likewise, nf-next is merged into net-next.

Before send the patch, I'll read the MAINTAINERS file, and search in 
email-list to confirm the correct subject.


And if need a new subject patch, i could resend a new one.




If it is a fix, then I would suggest targeting it at 'nf'
and providing a Fixes tag.

I'll keep it in mind in the future.


The above notwithstanding, this looks good to me.

Hi Kunwu,

nf is for fixes for Netfilter (which includes IPVS). The target tree is nf.git
nf-next is for non-fixes for Netfilter. The target tree if nf-next.git

net is for fixes for Networking code, which does not have a more specific
tree (as is the case for Netfilter). The target tree is net.git.
Liikewise, net-next is for non-fixes for Networking code.
The target tree is net-next.git

[PATCH net] ipvs: Simplify the allocation of ip_vs_conn slab caches

2024-01-16 Thread Kunwu Chan
Use the new KMEM_CACHE() macro instead of direct kmem_cache_create
to simplify the creation of SLAB caches.
