From f42eed7cba7f83197b0ffbb023e7d89a0b2fd71d Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Mon, 30 May 2011 14:45:30 +0300 Subject: UBIFS: harmonize znode flag helpers We have 3 znode flags: cow, obsolete, dirty. For the last flag we have a 'ubifs_zn_dirty()' helper function, but for the other 2 flags we use 'test_bit()' directly. This patch makes the situation more consistent and introduces helpers for the other 2 flags: 'ubifs_zn_cow()' and 'ubifs_zn_obsolete()'.
