0001 Clearing WARN_ONCE
0002 ------------------
0003 
0004 WARN_ONCE / WARN_ON_ONCE / printk_once only emit a message once.
0005 
0006 echo 1 > /sys/kernel/debug/clear_warn_once
0007 
0008 clears the state and allows the warnings to print once again.
0009 This can be useful after test suite runs to reproduce problems.
