Subject: tracing: Make tracing_selftest_running global to the tracing subsystem
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a4f77ffc8eb6247ad00c53d297a145e47594ce76;p=thirdparty%2Fkernel%2Fstable.git

tracing: Make tracing_selftest_running global to the tracing subsystem

The file trace.c has become a catchall for most things tracing. Start
making it smaller by breaking out various aspects into their own files.

Make the variable tracing_selftest_running global so that it can be used
by other files in the tracing subsystem and trace.c can be split up.
