The linux-next integration testing tree

Expose min_wait_usec in io_uring_getevents_arg, replacing the pad member that is currently in there. The value is in usecs, which is explained in the name as well. Note that if min_wait_usec and a normal timeout is used in conjunction, the normal timeout is still relative to the base time. For example, if min_wait_usec is set to 100 and the normal timeout is 1000, the max total time waited is still 1000. This also means that if the normal timeout is shorter than min_wait_usec, then only the min_wait_usec will take effect. See previous commit for an explanation of how this works. IORING_FEAT_MIN_TIMEOUT is added as a feature flag for this, as applications doing submit_and_wait_timeout() style operations will generally not see the -EINVAL from the wait side as they return the number of IOs submitted. Only if no IOs are submitted will the -EINVAL bubble back up to the application. Signed-off-by: Jens Axboe <axboe@kernel.dk> |

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 reStructuredText 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.
