Clearing WARN_ONCE
|
|
------------------
|
|
|
|
WARN_ONCE / WARN_ON_ONCE / printk_once only emit a message once.
|
|
|
|
echo 1 > /sys/kernel/debug/clear_warn_once
|
|
|
|
clears the state and allows the warnings to print once again.
|
|
This can be useful after test suite runs to reproduce problems.
