From dbc883f1570d992ba926a8c9e22140ba473c6cc1 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 13 Jan 2011 20:00:00 +0000 Subject: dm log: use PTR_ERR value instead of ENOMEM It's nicer to return the PTR_ERR() value instead of just returning -ENOMEM. In the current code the PTR_ERR() value is always equal to -ENOMEM so this doesn't actually affect anything, but still... In addition, dm_dirty_log_create() doesn't check for a specific -ENOMEM return. So this change is safe relative to potential for a non -ENOMEM return in the future.
