From dc141a402b9dc03a4188cd978a4cf149c397172c Mon Sep 17 00:00:00 2001 From: Ashish Sangwan Date: Sat, 21 Jul 2012 16:35:17 +0530 Subject: UDF: During mount free lvid_bh before rescanning with different blocksize If s_lvid_bh is not freed and set to NULL before re-scanning partition with default block size, we might end up using wrong lvid in case s_lvid_bh is not updated in udf_load_logicalvolint during rescan.
