ftrace: Remove unused pointer ftrace_swapper_pid
Pointer ftrace_swapper_pid is defined but is never used hence it is redundant and can be removed. The use of this variable was removed in commit 345ddcc882d8 ("ftrace: Have set_ftrace_pid use the bitmap like events do"). Cleans up clang warning: warning: 'ftrace_swapper_pid' defined but not used [-Wunused-const-variable=] Link: http://lkml.kernel.org/r/20180809125609.13142-1-colin.king@canonical.com Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
