Jens Axboe 980ad26304 io_uring: don't attempt to copy iovec for READ/WRITE 
For the non-vectored variant of READV/WRITEV, we don't need to setup an
async io context, and we flag that appropriately in the io_op_defs
array. However, in fixing this for the 5.5 kernel in commit 74566df3a7
we didn't have these opcodes, so the check there was added just for the
READ_FIXED and WRITE_FIXED opcodes. Replace that check with just a
single check for needing async context, that covers all four of these
read/write variants that don't use an iovec.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
