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.

Now we allocate io_mapped_ubuf instead of bvec, so we clearly have to check its address after allocation. Fixes: 41edf1a5 ("io_uring: keep table of pointers to ubufs") Reported-by:kernel test robot <lkp@intel.com> Signed-off-by:
