[RFC PATCH 7/7] audit: wake up kauditd_thread after auditd registers

Show all headers | View raw

When auditd is restarted, even though the kauditd_thread is present, it
remains dormant until the next audit log message is queued.

Wake up the kauditd_thread in the kauditd_wait queue immediately when
auditd registers its availability to drain the queue.
