Description

In llog_cat_process_cb() when we check for a positive startidx we should also check if the catindex matches (since the log at catindex may have been deleted):

static int llog_cat_process_cb(const struct lu_env *env,
                               struct llog_handle *cat_llh,
                               struct llog_rec_hdr *rec, void *data)
{
        /* ... */

        if (rec->lrh_index < d->lpd_startcat) {
                /* Skip processing of the logs until startcat */
                rc = 0;
        } else if (d->lpd_startidx > 0) { /* HERE */
                struct llog_process_cat_data cd;

                cd.lpcd_first_idx = d->lpd_startidx;
                cd.lpcd_last_idx = 0;
                rc = llog_process_or_fork(env, llh, d->lpd_cb, d->lpd_data,
                                          &cd, false);
                /* Continue processing the next log from idx 0 */
                d->lpd_startidx = 0;
        } else {
                rc = llog_process_or_fork(env, llh, d->lpd_cb, d->lpd_data,
                                          NULL, false);
        }
