Patch series "add epoll_pwait2 syscall", v4. Enable nanosecond timeouts for epoll. Analogous to pselect and ppoll, introduce an epoll_wait syscall variant that takes a struct timespec instead of int timeout. This patch (of 4): Make epoll more consistent with select/poll: pass along the timeout as timespec64 pointer. In anticipation of additional changes affecting all three polling mechanisms: - add epoll_pwait2 syscall with timespec semantics, and share poll_select_set_timeout implementation. - compute slack before conversion to absolute time, to save one ktime_get_ts64 call.

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.
