This adds ~80 bytes of .text for a saving of ~1.5K of data in my builds. Note the format changes from print fmt: "success=%d dependency=%s", REC->success, __print_symbolic(REC->dependency, { 0, "NONE" }, { (1 << 0), "POSIX_TIMER" }, { (1 << 1), "PERF_EVENTS" }, { (1 << 2), "SCHED" }, { (1 << 3), "CLOCK_UNSTABLE" }, { (1 << 4), "RCU" }, { (1 << 5), "RCU_EXP" }) to print fmt: "success=%d dependency=%s", REC->success, __print_symbolic(REC->dependency, { 0, "NONE" }, { 1, "POSIX_TIMER" }, { 2, "PERF_EVENTS" }, { 4, "SCHED" }, { 8, "CLOCK_UNSTABLE" }, { 16, "RCU" }, { 32, "RCU_EXP" }) since the values are now just printed in the show function as pure decimal values.
