From e4d9b6cbfc98d696a28d2c24a3d49768695811ee Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Fri, 23 Jan 2009 14:17:36 +0200 Subject: UBIFS: fix LEB list freeing When freeing the c->idx_lebs list, we have to release the LEBs as well, because we might be called from mount to read-only mode code. Otherwise the LEBs stay taken forever, which may cause problems when we re-mount back ro RW mode.
