Ocfs2 devel - Mar 2014 - [PATCH] ocfs2: iput inode alloc when failed locally

In ocfs2_info_handle_freeinode() and ocfs2_test_inode_bit() func,
after calls ocfs2_get_system_file_inode() to get inode ref, if
calls ocfs2_info_scan_inode_alloc() or ocfs2_inode_lock() failed,
we should iput inode alloc to avoid inode alloc be left over.
