No, because I haven't received it :-) You've sent it as an HTML message it it 
thus got dropped by the mailing list. Please don't send HTML e-mails.

While at it, when submitting a new version of a patch, please indicate that in 
the subject line. It should have been [PATCH v2]. Otherwise it's difficult for 
us to figure out if the patch is a duplicate or a new version, or to find the 
latest version.

Don't you notice something wrong in those last two lines ?
