as it is, the logics in native io_submit(2) is "if asked for more than LONG_MAX/sizeof(pointer) iocbs to submit, don't bother with more than LONG_MAX/sizeof(pointer)" (i.e. 512M requests on 32bit and 1E requests on 64bit) while compat io_submit(2) goes with "stop after the first PAGE_SIZE/sizeof(pointer) iocbs", i.e. 1K or so. Which is * inconsistent * *way* too much in native case * possibly too little in compat one and * wrong anyway, since the natural point where we ought to stop bothering is ctx->nr_events Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
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.
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.
