From e81f1c5c4a6e2c72add88ec596aaf942e9fcf30b Mon Sep 17 00:00:00 2001 From: Joseph Qi Date: Tue, 26 Jul 2016 15:21:44 -0700 Subject: ocfs2: remove obscure BUG_ON in dlmglue These BUG_ON(!inode) are obscure because we have already used inode to get osb. And actually we can guarantee here inode is valid in the context. So we can safely remove them.
