For a patch by any other author I'd be fine with -fsdevel, but for this specific one (because it's written by me and I'm not yet so bofh that I review my own patches ;)) someone else from the xfs community has to review it, so yes I'd like it to be sent to linux-xfs, please. (And it's ok to note in the resend that this is the same as the -fsdevel series, but posted here to attract the attention of the other xfs developers.) --D
