Modified files:
sys/security/audit audit_pipe.c
Log:
- Change the wakeup logic associated with having multiple sleepers
on multiple different audit pipes. The old method used cv_signal()
which would result in only one thread being woken up after we
appended a record to it's queue. This resulted in un-timely wake-ups
when processing audit records real-time.
- Assign PSOCK priority to threads that have been sleeping on a read(2).
This is the same priority threads are woken up with when they select(2)
or poll(2). This yields fairness between various forms of sleep on
the audit pipes.
