From fdb76a4228303491b1b9b8923310f2cbcec8dc9f Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Mon, 2 Apr 2012 15:34:36 +0100 Subject: [PATCH] GFS2: Drop "pull" argument from log_write_header() The "pull" argument to log_write_header() is only used for debug purposes and it is not really needed any more. There are other tests for this particular problem, so I think we can dispose of it in order to simplify the code.
