From cda95406c8fe491c01b3abc422c25a613e9f36ea Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 27 Feb 2013 17:03:44 -0800 Subject: dlm: use idr_for_each_entry() in recover_idr_clear() error path Convert recover_idr_clear() to use idr_for_each_entry() instead of idr_for_each(). It's somewhat less efficient this way but it shouldn't matter in an error path. This is to help with deprecation of idr_remove_all().
