From c01f36a896cb11e8533b4f7c132a1722fb15102b Mon Sep 17 00:00:00 2001 From: Steve French Date: Tue, 30 May 2006 18:05:10 +0000 Subject: [CIFS] ACPI suspend oops Wasn't able to reproduce a hard hang, but was able to get an oops if suspended the machine during a copy to the cifs mount. This led to some things hanging, including a "sync". Also got I/O errors when trying to access the mount afterwards (even when didn't see the oops), and had to unmount and remount in order to access the filesystem. This patch fixed the oops.
