8659 static dtrace probes unavailable on non-GPL modules
ZFS tracing efforts are hampered by the inability to access zfs static probes(probes using DTRACE_PROBE macros). The probes are available via tracepoints for GPL modules only. The build could be modified to generate a function for each unique DTRACE_PROBE invocation. These could be then accessed via kprobes.

/*
|

* Calls to DTRACE_PROBE* are mapped to standard Linux kernel trace points
|
||||
* when they are available(when HAVE_DECLARE_EVENT_CLASS is defined). The
|
||||
* tracepoint event class definitions are found in the general tracing
|
||||
* header file: include/sys/trace_*.h. See include/sys/trace_vdev.h for
|
||||
* a good example.
|
||||
*
|
||||
* If tracepoints are not available, stub functions are generated which can
|
||||
* be traced using kprobes. In this case, the DEFINE_DTRACE_PROBE* macros
|
||||
* are used to provide the stub functions and also the prototypes for
|
||||
* those functions. The mechanism to do this relies on DEFINE_DTRACE_PROBE
|
||||
* macros defined in the general tracing headers(see trace_vdev.h) and
|
||||
* CREATE_TRACE_POINTS being defined only in module/zfs/trace.c. When ZFS
|
||||
* source files include the general tracing headers, e.g.
|
||||
* module/zfs/vdev_removal.c including trace_vdev.h, DTRACE_PROBE calls
|
||||
* are mapped to stub functions calls and prototypes for those calls are
|
||||
* declared via DEFINE_DTRACE_PROBE*. Only module/zfs/trace.c defines
|
||||
* CREATE_TRACE_POINTS. That is follwed by includes of all the general
|
||||
* tracing headers thereby defining all stub functions in one place via
|
||||
* the DEFINE_DTRACE_PROBE macros.
|
||||
*
|
||||
* When adding new DTRACE_PROBEs to zfs source, both a tracepoint event
|
||||
* class defintition and a DEFINE_DTRACE_PROBE definition are needed to
|
||||
* avoid undefined function errors.
