Subject: tcp: Remove check in __tcp_push_pending_frames
X-Git-Tag: v2.6.34-rc1~233^2~719
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=12d50c46dc0f7fd2e625c4befaa5fa5740a7a594;p=pandora-kernel.git

tcp: Remove check in __tcp_push_pending_frames

tcp_push checks tcp_send_head and calls __tcp_push_pending_frames,
which again checks tcp_send_head, and this unnecessary check is
done for every other caller of __tcp_push_pending_frames.

Remove tcp_send_head check in __tcp_push_pending_frames and add
the check to tcp_push_pending_frames. Other functions call
__tcp_push_pending_frames only when tcp_send_head would evaluate
to true.
