[PATCH 14/21] netfilter: nf_ct_expect: nf_ct_expect_insert() returns void

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

 



From: Gao Feng <fgao@xxxxxxxxxx>

Because nf_ct_expect_insert() always succeeds now, its return value can
be just void instead of int. And remove code that checks for its return
value.
