USB: otg: fix module reinsert issue
[linux-2.6] / include / trace / define_trace.h
1 /*
2  * Trace files that want to automate creationg of all tracepoints defined
3  * in their file should include this file. The following are macros that the
4  * trace file may define:
5  *
6  * TRACE_SYSTEM defines the system the tracepoint is for
7  *
8  * TRACE_INCLUDE_FILE if the file name is something other than TRACE_SYSTEM.h
9  *     This macro may be defined to tell define_trace.h what file to include.
10  *     Note, leave off the ".h".
11  *
12  * TRACE_INCLUDE_PATH if the path is something other than core kernel include/trace
13  *     then this macro can define the path to use. Note, the path is relative to
14  *     define_trace.h, not the file including it. Full path names for out of tree
15  *     modules must be used.
