Currently the code doesn't recognize asynchronous calls passed by io_submit() and processes all calls synchronously. This is not what kernel AIO expects. This patch introduces a new async context that keeps track of all issued i/o requests and moves a response collecting procedure to a separate thread. This allows to return to a caller immediately for async calls and call iocb->ki_complete() once all requests are completed. For sync calls the current thread simply waits until all requests are completed. Signed-off-by: Pavel Shilovsky <pshilov@microsoft.com> Signed-off-by: Steve French <smfrench@gmail.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
