hi, I built multipath-tool with -Wextra and gcc shows a lot of warnings. But I believe two of them are relevant: log_pthread.c:37:3: warning: implicit declaration of function ‘syslog’ [-Wimplicit-function-declaration] - missing header <syslog.h> dasd.c:233:4: warning: comparison is always false due to limited range of data type [-Wtype-limits] - wrong type -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
