4Subject: [PATCH 02/10] Fix: tracepoint event: allow same provider and event
5 name
6
7Using the same name for the provider (TRACE_SYSTEM) and event name
8causes a compilation error because the same identifiers are emitted
9twice.
10
11Fix this by prefixing the provider identifier with
12"__provider_event_desc___".

9 commit fa2c3254d7cfff5f7a916ab928a562d1165f17bb

13 sched/tracing: Don't re-read p->state when emitting sched_switch event
14
15 As of commit
16
17 c6e7bd7afaeb ("sched/core: Optimize ttwu() spinning on p->on_cpu")
18
19 the following sequence becomes possible:
20
21 p->__state = TASK_INTERRUPTIBLE;
22 __schedule()
23 deactivate_task(p);
24 ttwu()
25 READ !p->on_rq
26 p->__state=TASK_WAKING
27 trace_sched_switch()
28 __trace_sched_switch_state()
29 task_state_index()
30 return 0;
31
32 TASK_WAKING isn't in TASK_REPORT, so the task appears as TASK_RUNNING in
33 the trace event.
34
35 Prevent this by pushing the value read from __schedule() down the trace
36 event.

12 block: remove genhd.h
13
14 There is no good reason to keep genhd.h separate from the main blkdev.h
15 header that includes it. So fold the contents of genhd.h into blkdev.h
16 and remove genhd.h entirely.

12 random: remove unused tracepoints
13
14 These explicit tracepoints aren't really used and show sign of aging.
15 It's work to keep these up to date, and before I attempted to keep them
16 up to date, they weren't up to date, which indicates that they're not
17 really used. These days there are better ways of introspecting anyway.

13 kprobes: Use rethook for kretprobe if possible
14
15 Use rethook for kretprobe function return hooking if the arch sets
16 CONFIG_HAVE_RETHOOK=y. In this case, CONFIG_KRETPROBE_ON_RETHOOK is
17 set to 'y' automatically, and the kretprobe internal data fields
18 switches to use rethook. If not, it continues to use kretprobe
19 specific function return hooks.

13 mm: compaction: cleanup the compaction trace events

15 As Steven suggested [1], we should access the pointers from the trace
16 event to avoid dereferencing them to the tracepoint function when the
17 tracepoint is disabled.
