From 37ebb54915dc42944f6ae92fe53b9531c3903801 Mon Sep 17 00:00:00 2001 From: Petr Mladek Date: Fri, 19 Sep 2014 17:32:23 +0200 Subject: usb: hub: rename khubd to hub_wq in documentation and comments USB hub has started to use a workqueue instead of kthread. Let's update the documentation and comments here and there. This patch mostly just replaces "khubd" with "hub_wq". There are only few exceptions where the whole sentence was updated. These more complicated changes can be found in the following files: Documentation/usb/hotplug.txt drivers/net/usb/usbnet.c drivers/usb/core/hcd.c drivers/usb/host/ohci-hcd.c drivers/usb/host/xhci.c Signed-off-by: Petr Mladek Acked-by: Alan Stern Signed-off-by: Greg Kroah-Hartman --- Documentation/usb/WUSB-Design-overview.txt | 6 +++--- Documentation/usb/hotplug.txt | 2 +- 2 files changed, 4 insertions(+), 4 deletions(-) (limited to 'Documentation/usb') diff --git a/Documentation/usb/WUSB-Design-overview.txt b/Documentation/usb/WUSB-Design-overview.txt index 512238c3dc86..fdb47637720e 100644 --- a/Documentation/usb/WUSB-Design-overview.txt +++ b/Documentation/usb/WUSB-Design-overview.txt @@ -308,7 +308,7 @@ HC picks the /DN_Connect/ out (nep module sends to notif.c for delivery into /devconnect/).
