Subject: tcp: remove an unnecessary check in tcp_tx_timestamp
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=863c1fd9814618eefba02218f8fadf8a430c2a17;p=deliverable%2Flinux.git

tcp: remove an unnecessary check in tcp_tx_timestamp

Remove the redundant check for sk->sk_tsflags in tcp_tx_timestamp.

tcp_tx_timestamp() receives the tsflags as a parameter. As a
result the "sk->sk_tsflags || tsflags" is redundant, since
tsflags already includes sk->sk_tsflags plus overrides from
control messages.
