--- Comment #6 from Bart Van Assche (bvanass...@acm.org) ---
The "size=4104" in the error message probably refers to the SCSI log buffer.
>From drivers/scsi/scsi_logging.c:
#define SCSI_LOG_SPOOLSIZE 4096
struct scsi_log_buf {
char buffer[SCSI_LOG_SPOOLSIZE];
unsigned long map;
};
static DEFINE_PER_CPU(struct scsi_log_buf, scsi_format_log);
I am not aware of any changes between kernel versions v5.1 and v5.2 in the SCSI
logging mechanism so I don't think that this indicates a regression in the SCSI
subsystem. Anyway, does this patch help?
