5.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Uros Bizjak <ubizjak@xxxxxxxxx> [ Upstream commit eb887c4567d1b0e7684c026fe7df44afa96589e6 ] Use atomic64_inc_return(&ref) instead of atomic64_add_return(1, &ref) to use optimized implementation and ease register pressure around the primitive for targets that implement optimized variant.
