From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Wolfgang Bumiller Date: Wed, 29 Nov 2017 11:11:46 +0100 Subject: [PATCH] block/file: change locking default to off 'auto' only checks whether the system generally supports OFD locks but not whether the storage the file resides on supports any locking, causing issues with NFS.
