Subject: efivarfs and writev() support

Hi,

it seems that efivarfs only supports readv(), but when it comes to writev(), I am getting an error. Is there any reason to not support vectored write on this filesystem? Especially with the uint32 header for each file, I think it would make perfect sense to support it.

Regards

Marcel
