From bc85178a7668db835666c6a5bd53436eebfc94b1 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Fri, 6 Jun 2014 15:20:54 +1000 Subject: [PATCH] xfs: remove mp->m_dir_geo from directory logging We don't pass the xfs_da_args or the geometry all the way down to the directory buffer logging code, hence we have to use mp->m_dir_geo here. Fix this to use the geometry passed via the xfs_da_args, and convert all the directory logging functions for consistency.
