The following patch fixes svc_tcp_has_wspace() so that we only stop processing requests if we know that the socket buffer cannot possibly fit another reply. It also fixes the tcp write_space() callback so that we only clear the SOCK_NOSPACE flag when the TCP send buffer is less than 2/3 full. This should ensure that the send window will grow as per the standard TCP socket code. Signed-off-by: Trond Myklebust Signed-off-by: J. Bruce Fields --- Reading git-diff-tree failed
