All socket operations on the SMC socket are then > forwarded to the TCP socket. In case of poll, the file->private_data > pointer references the SMC socket because the TCP socket has no file > assigned. This causes tcp_poll to wait on the wrong socket. > > Signed-off-by: Karsten Graul <kgraul@xxxxxxxxxxxxx> Applied and queued up for -stable, thank you.
