[Ocfs2-devel] Garbage ERESTARTSYS in dlmdomain.c?

[Joel Becker <Joel.Becker@oracle.com>]

Look at this code from dlmdomain.c:

-----------------------------------------------------------------------
                /* If we're racing another node to the join, then we
                 * need to back off temporarily and let them
                 * complete. */
#define DLM_JOIN_TIMEOUT_MSECS  90000
                if (status == -EAGAIN) {
                        if (signal_pending(current)) {
                                status = -ERESTARTSYS;
                                goto bail;
                        }

                        if (total_backoff >
                            msecs_to_jiffies(DLM_JOIN_TIMEOUT_MSECS)) {
                                status = -ERESTARTSYS;
                                mlog(ML_NOTICE, "Timed out joining dlm domain "
                                     "%s after %u msecs\n", dlm->name,
                                     jiffies_to_msecs(total_backoff));
                                goto bail;
                        }
-----------------------------------------------------------------------

Why are we returning -ERESTARTSYS when there isn't a signal pending?
This seems like it could totally do something weird, like have entry.S
get confused.
