#29 iscsictl to be replaced with ietctl in log_error message in ctldev

[Devendra Tapdia]

Device file name is ietctl but log_error has iscsictl in error message

usr/ctldev.c

log_error("cannot find iscsictl in /proc/devices - "
"make sure the kernel module is loaded");

Should be replaced with

log_error("cannot find ietctl in /proc/devices - "
"make sure the kernel module is loaded");
