The linux-next integration testing tree

On 64-bit platforms, userspace can read the pidfd's inode in order to get a never-repeated PID identifier. On 32-bit platforms this identifier is not exposed, as inodes are limited to 32 bits. Instead expose the identifier via export_fh, which makes it available to userspace via name_to_handle_at. In addition we implement fh_to_dentry, which allows userspace to recover a pidfd from a pidfs file handle.

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 reStructuredText 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.
