Alison Schofield 4234d4f8b4 cxl/trace: Properly initialize cxl_poison region name ... [ Upstream commit 6c87126096 ] The TP_STRUCT__entry that gets assigned the region name, or an empty string if no region is present, is erroneously initialized to the cxl_region pointer. It needs to be properly initialized otherwise it's length is wrong and garbage chars can appear in the kernel trace output: /sys/kernel/tracing/trace The bad initialization was due in part to a naming conflict with the parameter: struct cxl_region *region. The field 'region' is already exposed externally as the region name, so changing that to something logical, like 'region_name' is not an option. Instead rename the internal only struct cxl_region to the commonly used 'cxlr'. Impact is that tooling depending on that trace data can miss picking up a valid event when searching by region name. The TP_printk() output, if enabled, does emit the correct region names in the dmesg log. This was found during testing of the cxl-list option to report media-errors for a region.
