I asked this question yesterday on superuser but got no answer so I figured I'd try the kernel mailing list next. Unfortunately, the FAQ mentions that it's for development only and they don't appear to provide a list for users: "User space issues are not appropriate for this forum.". What are other good places to ask user space questions about the Linux kernel?
I don't know of any other places outside the Stack Exchange network, but your question would also be suited for Unix & Linux.
If you want it moved, flag it for moderator attention and we'll migrate it there – don't cross-post, please.
