From 783b273afab43437dca731a229d53d72faf77fd3 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Tue, 25 Dec 2007 18:13:33 +0200 Subject: UBI: use separate mutex for volumes checking Introduce a separate mutex which serializes volumes checking, because we cammot really use volumes_mutex - it cases reverse locking problems with mtd_tbl_mutex when gluebi is used - thanks to lockdep.
