From 77c06202484237e26774efbd1774c251b6bef0a9 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Thu, 14 Jul 2011 15:27:16 +1000 Subject: [PATCH] xfstests: fix brain-o in fallocate log dump fsx segvs when dumping fallocate log entries. Fix magic string array index parameters to be zero based rather than one based. While touching log string related stuff, make the format consistent with read and write operations so the log dump is easier to look at with the human eye.
