From 25869262ef7af24ccde988867ac3eb1c3d4b88d4 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sat, 17 Sep 2016 21:02:10 -0400 Subject: skb_splice_bits(): get rid of callback since pipe_lock is the outermost now, we don't need to drop/regain socket locks around the call of splice_to_pipe() from skb_splice_bits(), which kills the need to have a socket-specific callback; we can just call splice_to_pipe() and be done with that.
