The size argument to kcalloc should be the size of desired structure,

xsk_pools is a double pointer, so not "desired structure" but rather you
should talk about an element size.

not the pointer to it.

Fixes: 6402528b7a0b ("nfp: xsk: add AF_XDP zero-copy Rx and Tx support")

even if the the behavior is not changed, the fix should be targeted to
net tree

This patch is IMHO more a cleanup than a real fix. As such it's more
suited for net-next. For the same reason I think it should not go to
stable, so I'm dropping the fixes tag, too.

I'm fine with targeting it at any of the trees.

But I still believe it is a fix, even if a trivial one, and even if code
"works" - it's a "wrong" code.

Here I received similar feedback in a similar case:
https://www.mail-archive.com/intel-wired-lan@xxxxxxxxxx/msg03252.html
and I changed my mind then.


Thinking again about it, this patch has a few things to be cleaned-up.

@Chen Ni, please submit a new revision, adjusting the subj and commit
message as per Przemek and Simon feedback and dropping the fixes tag,
still targeting net-next.

You can retain the already collected tags.

Thanks,

Paolo
