Like patching syscall tables in OSes that do not explicitly support it. Or having it's own cache flushing code in assemly instead of using readily-available OS code. Or hooking into the NFS server through binary patching and overriding some of it's functionality, or dozends of other things that I could mention. > > For those using afs there is an in-kernel client > > that has seen a lot of work lately and will be support all features > > of openafs soon while fixing all these issues.

I don't think there is any point in tracking OpenAFS code. It's of absymal code quality, and under a strange license that wouldn't even allow to reuse a piece of good code if you managed to find it. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
