Jeff has been busy today I see...
What is the current status about OpenAFS and Linux threads? I know the thread situation on Linux sucks in general, just tell me your best practice, ok? :-)
Ok. My best practice is to run fileservers on SPARC Solaris, thereby avoiding the Linux threads mess, the horrible kludge that is the namei fileserver, and all sorts of other problems that the rest of you have seen.

Really, I can't tell you much about OpenAFS and Linux threads. Maybe Derrick can field that one.
The last bug I knew of (Linux fileserver hangs with new-style Linux threads) was the one we were suggesting LD_ASSUME_KERNEL 2.4.0 for. The 1.2.13/1.3.74 changes seem to have addressed it (caveat; I did not test for that particular bug exhaustively at the time). Other than that, no issues known to me. The old-style Linux threads had been seen to have the issue that a single thread's cloned pid could die and leave the fileserver otherwise running but unhappy. All cases I knew of where this actually happened were triggered by other bugs.
