From 48ef09a16edcc98d1de60f66ed7f650c571907f4 Mon Sep 17 00:00:00 2001 From: Satyam Sharma Date: Tue, 16 Oct 2007 23:26:53 -0700 Subject: [PATCH] ufs: Fix mount check in ufs_fill_super() The current code skips the check to verify whether the filesystem was previously cleanly unmounted, if (flags & UFS_ST_MASK) == UFS_ST_44BSD or UFS_ST_OLD. This looks like an inadvertent bug that slipped in due to parantheses in the compound conditional to me, especially given that ufs_get_fs_state() handles the UFS_ST_44BSD case perfectly well. So, let's fix the compound condition appropriately.
