This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: aio: kill pointless ki_nbytes assignment in aio_setup_single_vector
From: "Chen, Kenneth W" <kenneth.w.chen@xxxxxxxxx>
io_submit_one assigns ki_left = ki_nbytes = iocb->aio_nbytes, then calls
down to aio_setup_iocb, then to aio_setup_single_vector. In there,
ki_nbytes is reassigned to the same value it got two call stack above it.
There is no need to do so.
