For some reason it didn't show up in my mailbox; maybe an errant SPAM checker grabbed it? (For some reason Herbert Xu's mail server recently blacklisted my mail server, so he can't get any e-mails from me, whether it's a reply to LKML or an invite to the kernel summit. More recently Baracuda Networks, which handles mit.edu's spam filtering, blacklisted the mail server for the vendor-sec mailing list. Go figure.) Fortunately your patch did show up in patchwork: http://patchwork.ozlabs.org/project/linux-ext4/ I've been travelling, so I haven't had a chance to look at it, although I did note that it had showed up over the weekend when I was going over the patch queue and reconciling it with Patchwork, and wondered why I hadn't seen earlier... I will try to get it shortly. Regards, - Ted
