[Patch bpf-next v2 3/4] skmsg: save some space in struct sk_psock

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Cong Wang <cong.wang@xxxxxxxxxxxxx>

This patch aims to save some space in struct sk_psock and prepares for
the next patch which will add more fields.

psock->eval can only have 4 possible values, make it 8-bit is
sufficient.

psock->redir_ingress is just a boolean, using 1 bit is enough.
