This looks wrong because we are comparing a boolean with an
integer constant, ang gcc warns about it accordingly:
drivers/scsi/qla2xxx/qla_target.c: In function 'qlt_do_ctio_completion':
drivers/scsi/qla2xxx/qla_target.c:3587:20: warning: comparison of constant '41' with boolean expression is always false [-Wbool-compare]
(logged_out == CTIO_PORT_LOGGED_OUT) ?
The correct fix is presumably to make that variable an 'int'.

Hello Arnd,
Please read the e-mail thread that is available at
http://thread.gmane.org/gmane.linux.scsi/108899/focus=108943. That
thread namely makes it clear that the above patch is not the proper way
to fix that code.
Thanks,
Bart.
