From d147b3d630edef1d34de6ea819787a1ac1b8603b Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Wed, 7 Nov 2007 14:40:36 -0800 Subject: ocfs2: Support commit= mount option Mostly taken from ext3. This allows the user to set the jbd commit interval, in seconds. The default of 5 seconds stays the same, but now users can easily increase the commit interval. Typically, this would be increased in order to benefit performance at the expense of data-safety.
