From: Colin Ian King <redacted> In the case where sig is NULL the error variable ret is not initialized and may contain a garbage value on the final checks to see if ret is -ERESTARTSYS. Best to initialize ret to zero before the do loop to ensure the ret does not accidentially contain -ERESTARTSYS before the loop.
Oops, weird it didn't complain. I've folded in this fix, as that commit isn't upstream yet. Thanks! -- Jens Axboe
