Date: Thu, 5 Jul 2007 21:18:24 +0200 From: "Rafael J. Wysocki" <rjw@...k.pl> To: Andrew Morton <akpm@...ux-foundation.org> Cc: Len Brown <len.brown@...el.com>, Nigel Cunningham <nigel@...el.suspend2.net>, Pavel Machek <pavel@....cz>, LKML <linux-kernel@...r.kernel.org> Subject: [PATCH -mm 1/2] ACPI: Do not prepare for hibernation in acpi_shutdown From: Rafael J. Wysocki <rjw@...k.pl> Since we are now explicitly calling hibernation_ops->prepare() before hibernation_ops->enter() in hibernation_platform_enter() (defined in kernel/power/disk.c), ACPI should not call acpi_sleep_prepare(ACPI_STATE_S4) from acpi_shutdown().
