From 0811a127cb83ad2e0355e5e3e30164d7ef0f2d65 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Thu, 3 Jan 2008 09:24:53 -0600 Subject: [PATCH] [GFS2] Initialize extent_list earlier Here is a patch for the latest upstream GFS2 code: The journal extent map needs to be initialized sooner than it currently is. Otherwise failed mount attempts (e.g. not enough journals, etc.) may panic trying to access the uninitialized list.
