From: Wei Yongjun <weiyongjun1@xxxxxxxxxx> The sparse tool complains as follows: kernel/smp.c:107:10: warning: symbol 'csd_bug_count' was not declared. Should it be static? Because variable is not used outside of smp.c, this commit marks it static. Reported-by: Hulk Robot <hulkci@xxxxxxxxxx> Signed-off-by: Wei Yongjun <weiyongjun1@xxxxxxxxxx> Signed-off-by: Paul E.
