[ Upstream commit 3a689e34973e8717cd57991c6fcf527dc56062b5 ] tp->dirty_tx isn't changed outside rtl_tx(). Therefore I see no need to guarantee a specific order of reading tp->dirty_tx and tp->cur_tx. Having said that we can remove the memory barrier. In addition use READ_ONCE() when reading tp->cur_tx because it can change in parallel to rtl_tx().
