From: Jakob Koschel <jakobkoschel@xxxxxxxxx>
Subject: ocfs2: remove usage of list iterator variable after the loop body
To move the list iterator variable into the list_for_each_entry_*() macro
in the future it should be avoided to use the list iterator variable after
the loop body.
To *never* use the list iterator variable after the loop it was concluded
to use a separate iterator variable [1].
