So, I don't think the iov_iter stuff is the right approach for solving
the loop issue; it's an ugly hack and after immutable biovecs we're
pretty close to a better solution and some major cleanups too.
I don't know about ecryptfs and AIO for target, though - are there
patches for those you could point me at so I can have a look? I can
believe the iov_iter stuff is necessary for those, but I'd like to
convince myself there isn't a cleaner solution.
Regardless, I don't want to be blocking anyone else's work; if we do
want the iov_iter stuff in now (I'm not arguing one way or the other
till I look at the issues you pointed out) I can write a small patch to
correctly merge with immutable bvecs; I looked at it today and it's
pretty straightforward (if somewhat ugly).
