| 2016-12-09 | tracing: Have the reg function allow to fail | Steven Rostedt (Red Hat) | 1 | -1/+1 | |
| Some tracepoints have a registration function that gets enabled when the tracepoint is enabled. There may be cases that the registraction function must fail (for example, can't allocate enough memory). In this case, the tracepoint should also fail to register, otherwise the user would not know why the tracepoint is not working.

| 2016-03-15 | tracepoints: move trace_print_flags definitions to tracepoint-defs.h | Vlastimil Babka | 1 | -2/+12 | |
| The following patch will need to declare array of struct trace_print_flags in a header. To prevent this header from pulling in all of RCU through trace_events.h, move the struct trace_print_flags{_64} definitions to the new lightweight tracepoint-defs.h header.

| 2015-12-06 | tracepoints: Move struct tracepoint to new tracepoint-defs.h header | Andi Kleen | 1 | -0/+27 | |
| Steven recommended open coding access to tracepoint->key to add trace points to headers. Unfortunately this is difficult for some headers (such as x86 asm/msr.h) because including tracepoint.h includes so many other headers that it causes include loops. The main problem is the include of linux/rcupdate.h, which pulls in a lot of other headers. The rcu header is only needed when actually defining trace points. Move the struct tracepoint into a separate tracepoint-defs.h header that can be included without pulling in all of RCU.
