Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] USB: add endpoint information to sysfs This patch adds endpoint information for both devices and interfaces to sysfs. Previously it was only possible to get the endpoint information from usbfs, and never possible to get any information on endpoint 0.

/* endpoint stuff */
[PATCH] usbcore: Improve endpoint sysfs file handling This revised patch (as587b) improves the implementation of USB endpoint sysfs files. Instead of storing a whole bunch of attributes for every single endpoint, each endpoint now gets its own kobject and they can share a static list of attributes. The number of extra fields added to struct usb_host_endpoint has been reduced from 4 to 1. The bEndpointAddress field is retained even though it is redundant (it repeats the same information as the attributes' directory name). The code avoids calling kobject_register, to prevent generating unwanted hotplug events. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
