From 4327a9bf71f4b021b675e01f24fefc647cff7513 Mon Sep 17 00:00:00 2001 From: Bob Peterson <rpeterso@redhat.com> Date: Mon, 12 Nov 2012 13:03:29 -0500 Subject: GFS2: Eliminate redundant buffer_head manipulation in gfs2_unlink_inode Since we now have a dirty_inode that takes care of manipulating the inode buffer and writing from the inode to the buffer, we can eliminate some unnecessary buffer manipulations in gfs2_unlink_inode that are now redundant.
