Luiz Capitulino noticed that the tick_stop tracepoint wasn't being parsed properly by the tracing user space tools. This was due to the TRACE_DEFINE_ENUM() being set to a define, when it should have been set to the enum itself. The define was of the MASK that used the BIT to shift. The BIT was the enum and by adding that, everything gets converted nicely. The MASK is still kept just in case it gets converted to an enum in the future" * tag 'trace-v4.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Fix tick_stop tracepoint symbols for user export 2016-08-09T13:51:23Z Steven Rostedt (Red Hat) rostedt@goodmis.org 2016-08-05T16:41:52Z urn:sha1:c87edb36118664f1fa275107c1138b6f47793240 The symbols used in the tick_stop tracepoint were not being converted properly into integers in the trace_stop format file. Instead we had this: print fmt: "success=%d dependency=%s", REC->success, __print_symbolic(REC->dependency, { 0, "NONE" }, { (1 << TICK_DEP_BIT_POSIX_TIMER), "POSIX_TIMER" }, { (1 << TICK_DEP_BIT_PERF_EVENTS), "PERF_EVENTS" }, { (1 << TICK_DEP_BIT_SCHED), "SCHED" }, { (1 << TICK_DEP_BIT_CLOCK_UNSTABLE), "CLOCK_UNSTABLE" }) User space tools have no idea how to parse "TICK_DEP_BIT_SCHED" or the other symbols used to do the bit shifting. The reason is that the conversion was done with using the TICK_DEP_MASK_* symbols which are just macros that convert to the BIT shift itself (with the exception of NONE, which was converted properly, because it doesn't use bits, and is defined as zero). The TICK_DEP_BIT_* needs to be denoted by TRACE_DEFINE_ENUM() in order to have this properly converted for user space tools to parse this event.

This means that old code that relies on manually setting bi_rw is most likely going to be broken. Instead of letting that brokeness linger, rename the member, to force old and out-of-tree code to break at compile time instead of at runtime. No intended functional changes in this commit.
