Date: Mon, 1 Sep 2014 12:26:51 +0200 From: Ricardo Ribalda Delgado <ricardo.ribalda@...il.com> To: Mathias Nyman <mathias.nyman@...el.com> Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Linux USB Mailing List <linux-usb@...r.kernel.org>, LKML <linux-kernel@...r.kernel.org> Subject: Re: [PATCH] xhci-ring: Fix Null pointer dereference Well, it is hard to say. rc2 without the patch showed more warnings, but never crashed badly (queuecommand_lck....). The sample size is not big enough. maybe rc2 also has the queuecommand_lck bug, but I havent hit it.
