Merge KASAN word-at-a-time fixups from Andrey Ryabinin. The word-at-a-time optimizations have caused headaches for KASAN, since the whole point is that we access byte streams in bigger chunks, and KASAN can be unhappy about the potential extra access at the end of the string. We used to have a horrible hack in dcache, and then people got complaints from the strscpy() case. This fixes it all up properly, by adding an explicit helper for the "access byte stream one word at a time" case. * emailed patches from Andrey Ryabinin <aryabinin@virtuozzo.com>: fs: dcache: Revert "manually unpoison dname after allocation to shut up kasan's reports" fs/dcache: Use read_word_at_a_time() in dentry_string_cmp() lib/strscpy: Shut up KASAN false-positives in strscpy() compiler.h: Add read_word_at_a_time() function. compiler.h, kasan: Avoid duplicating __read_once_size_nocheck() |

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.
