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.

Since commit 67f9fd91, the code to wait for the read to complete has been dead. That commit wrongly stated that the read was synchronous already; this seems to have been a confusion about which ->readpage operation was being called. Instead of reintroducing an asynchronous version of read_mapping_page(), call the readahead code directly to submit all reads first before waiting for them in read_mapping_page().
