FreeBSD, Linux Kernel Source Cross Reference

An anonymous reader writes "Robert Watson of the FreeBSD Core Team has put up a FreeBSD and Linux kernel source cross reference based on the LXR software used for the Linux kernel cross reference. The stated purpose is to make it easier for FreeBSD users and developers to explore and understand the FreeBSD code, as well as to compare the FreeBSD approaches with abstractions and implementation in the Linux kernel. This should help with portability, compatibility, and architectural cleanliness. Robert has posted to the FreeBSD mailing lists indicating he'll be pushing source code for other *BSD systems and Darwin in the near future as well. Sounds like this may be a really useful site for FreeBSD developers, but also for all open source kernel developers (Linux and others)."
