This is mostly for linked timeouts, where if we ask for a pure timeout we always get -ETIME. This makes links useless for that case, hence allow a case where it works. - Five minor optimizations to fix and improve cases that regressed since v5.4. - An SQTHREAD locking fix. - A sendmsg/recvmsg iov assignment fix. - Net fix where read_iter/write_iter don't honor IOCB_NOWAIT, and subsequently ensuring that works for io_uring. - Fix a case where for an invalid opcode we might return -EBADF instead of -EINVAL, if the ->fd of that sqe was set to an invalid fd value. * tag 'io_uring-5.5-20191212' of git://git.kernel.dk/linux-block: io_uring: ensure we return -EINVAL on unknown opcode io_uring: add sockets to list of files that support non-blocking issue net: make socket read/write_iter() honor IOCB_NOWAIT io_uring: only hash regular files for async work execution io_uring: run next sqe inline if possible io_uring: don't dynamically allocate poll data io_uring: deferred send/recvmsg should assign iov io_uring: sqthread should grab ctx->uring_lock for submissions io-wq: briefly spin for new work after finishing work io-wq: remove worker->wait waitqueue io_uring: allow unbreakable links |

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.
