Jens Axboe 2e10dc9c2a io_uring/kbuf: don't truncate end buffer for multiple buffer peeks 
commit 26ec15e4b0 upstream.

If peeking a bunch of buffers, normally io_ring_buffers_peek() will
truncate the end buffer. This isn't optimal as presumably more data will
be arriving later, and hence it's better to stop with the last full
buffer rather than truncate the end buffer.
