[Ocfs2-devel] NULL pointer dereference in function ocfs2_abort_trigger
Hi all, Function ocfs2_abort_trigger() use bh->b_assoc_map to get super block. But I cannot find any function to set bh->b_assoc_map in ocfs2. So it will trigger NULL pointer dereference while calling this function. I am wonder that whether function t_abort->ocfs2_abort_trigger() can be deleted from ocfs2. Thanks very much.
