Jens Axboe 11ba820bf1 io_uring: ensure workqueue offload grabs ring mutex for poll list A previous commit moved the locking for the async sqthread, but didn't take into account that the io-wq workers still need it. We can't use req->in_async for this anymore as both the sqthread and io-wq workers set it, gate the need for locking on io_wq_current_is_worker() instead. Fixes: `8a4955ff1c` ("io_uring: sqthread should grab ctx->uring_lock for submissions") Reported-by: Bijan Mottahedeh <bijan.mottahedeh@oracle.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>		2020-01-15 21:51:17 -07:00

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.
