From d72244761b2230fbb2d6eaec59cdedd3ea651d4f Mon Sep 17 00:00:00 2001 From: Ankit Kumar Date: Fri, 21 Oct 2022 12:19:00 +0530 Subject: [PATCH] stat: fix segfault with fio option --bandwidth-log The log_params for aggregate read, write and trim only specify log type. As a result the io_log doesn't have the relevant thread_data structure. With fio option --bandwidth-log this results in segmentation fault. Add a check and use DEF_LOG_ENTRIES for such case.
