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.

Pull pidfd fork() fix from Christian Brauner: "A single small fix for copy_process() in kernel/fork.c: With Al's removal of ksys_close() from cleanup paths in copy_process() a bug was introduced. When anon_inode_getfile() failed the cleanup was correctly performed but the error code was not propagated to callers of copy_process() causing them to operate on a nonsensical pointer. The fix is a simple on-liner which makes sure that a proper negative error code is returned from copy_process(). syzkaller has also verified that the bug is not reproducible with this fix" * tag 'for-linus-20190701' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: fork: return proper negative error code
