In virtio 1.0 mode, when mergeable buffers are enabled on a big-endian
host, num_buffers wasn't byte-swapped correctly, so large incoming

it has just verified that it asks no more than the length of the
first segment of iovec.
And with that the last user of stuff in lib/iovec.c is gone.

Hmm having second thoughts here.
Will this modify the iov in vq-iov?
If yes, how will recvmsg fill it?
OK that was just me misunderstanding what the
function does. As it doesn't modify the iovec itself,
I think there's

This patch adds a new memcpy_fromiovec_out() library function which modifies
the passed *iov following memcpy_fromiovec(), but also returns the next

eventfd_fget() tests to see whether the file is an eventfd file, which

fdget() so that we only
pulling file.h; move that include there. Switch from eventfd_fget()/fput()
to fdget()/fdput(), while we are at it - eventfd_ctx_fileget() will fail
on non-eventfd descriptors just fine, no need to do that check twice...

FWIW, UINT_MAX is wrong here. What you want is maximal size_t value.
