*	blktrace: remove blk_probe_mutex	Li Zefan	2009-03-21
\| \| \| \| \| \| \| \| \| \| \| \| \|	blk_register_tracepoints() always returns 0, so make it return void, thus we don't need to use blk_probe_mutex to protect blk_probes_ref.

*	blktrace: make blk_tracer_enabled a bool flag	Li Zefan	2009-03-21
\| \| \| \| \| \| \| \| \| \| \| \|	It doesn't have to be a counter, and it can be a bool flag instead.

*	blktrace: fix possible memory leak	Li Zefan	2009-03-21
\| \| \| \| \| \| \| \| \| \| \| \| \|	When we failed to create "block" debugfs dir, we should do some cleanups.

*	tracing: protect reader of cmdline output	Steven Rostedt	2009-03-16
\| \| \| \| \| \| \| \| \| \| \| \| \|	Impact: fix to one cause of incorrect comm outputs in trace The spinlock only protected the creation of a comm <=> pid pair. But it was possible that a reader could look up a pid, and get the wrong comm because it had no locking. This also required changing trace_find_cmdline to copy the comm cache and not just send back a pointer to it. Signed-off-by: Steven Rostedt <srostedt@redhat.com>

*	tracing: remove extra latency_trace method from trace structure	Steven Rostedt	2009-03-04
\| \| \| \| \| \| \| \| \| \| \| \| \|	Impact: clean up The trace and latency_trace function pointers are identical for every tracer but the function tracer. The differences in the function tracer are trivial (latency output puts paranthesis around parent). This patch removes the latency_trace pointer and all prints will now just use the trace output function pointer. Signed-off-by: Steven Rostedt <srostedt@redhat.com>
