Staticise usb_ref_device and usb_unref_device.

MFC r207080

Use a more obvious prefix for the USB control (endpoint 0) transfers rather than default_*.

MFC r207079

2010-04-29T22:48:19Z

Properly name the sxlocks, mutexes and condvars.

MFC r199816

2009-12-09T22:42:40Z

Remove overuse of exclamation marks in kernel printfs, there mere fact a message has been printed is enough to get someones attention. Also remove the line number for DPRINTF/DPRINTFN, it already prints the funtion name and a unique message.

Provide tunables for some of the usb sysctls that affect boot behaviour. Submitted by: Andriy Gapon

Critical USB bugfixes for 8.0 Approved by: re

MFC 196403: Temporarily revert the new-bus locking for 8.0 release.

Approved by: re (kib)

Make the newbus subsystem Giant free by adding the new newbus sxlock.

2009-08-02T14:28:40Z

The newbus lock is responsible for protecting newbus internIal structures, device states and devclass flags. It is necessary to hold it when all such datas are accessed. For the other operations, softc locking should ensure enough protection to avoid races. Newbus lock is automatically held when virtual operations on the device and bus are invoked when loading the driver or when the suspend/resume take place. For other 'spourious' operations trying to access/modify the newbus topology, newbus lock needs to be automatically acquired and dropped. For the moment Giant is also acquired in some key point (modules subsystem) in order to avoid problems before the 8.0 release as module handlers could make assumptions about it. This Giant locking should go just after the release happens. Please keep in mind that the public interface can be expanded in order to provide more support, if there are really necessities at some point and also some bugs could arise as long as the patch needs a bit of further testing. Bump __FreeBSD_version in order to reflect the newbus lock introduction. Reviewed by: ed, hps, jhb, imp, mav, scottl No answer by: ariff, thompsa, yongari Tested by: pho, G.
