From 1e03b754aef576a5cb75f01b1805cdc1f9cc292f Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Thu, 4 Jun 2009 01:44:04 +0200 Subject: udevd: convert to event worker processes Event processes now get re-used after they handled an event. This reduces pressure on the CPU significantly because cloned event processes no longer cause page faults in the main daemon. After the events have settled, the no longer needed worker processes get killed. --- NEWS | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) (limited to 'NEWS') diff --git a/NEWS b/NEWS index ac44d7a77d..8b51c10a84 100644 --- a/NEWS +++ b/NEWS @@ -2,9 +2,17 @@ udev 143 ======== Bugfixes. +Event processes now get re-used after they handled an event.
