Hi All
My test results are as follows:
before this patch:
[ 49.919574] softirq: huh, entered softirq 1 TIMER 00000000bb45ef3a
with preempt_count 00000101, exited with 00000101?
after this patch:
[ 49.919570] softirq: huh, entered softirq 1 TIMER
run_timer_softirq+0x0/0x108 with preempt_count 00000101, exited with
00000102?
> preempt_count_set(prev_count);
