Subject: [RFC][PATCH -mm 3/7] Freezer: Prevent new tasks from inheriting TIF_FREEZE set
Date: Thu, 12 Jul 2007 00:12:03 +0200 [thread overview]
Message-ID: <200707120012.04747.rjw@sisk.pl> (raw)
In-Reply-To: <200707120006.50095.rjw@sisk.pl>
From: Rafael J. Wysocki <rjw@sisk.pl>
Tasks should go to the refrigerator only if explicitly requested to do that by
the freezer and not as a result of inheriting the TIF_FREEZE flag set from the
parent. Make it happen.
