Linux Device Drivers, Third Edition. Welcome to LWN.net. LXR / The Linux Cross Reference. What's new 2010-05-07 A badly timed hardware malfunction brought lxr.linux.no offline for several days. Thanks to the folks at Redpill Linpro for bringing the server back online -- apologies to everyone else for the interruption of service. 2010-02-06 A couple of rather embarrasing cross-site scripting holes have been plugged. Thanks to Dan Rosenberg and Moritz Naumann for bringing them to my attention.
