[ Upstream commit c6e8f898f56fae2cb5bc4396bec480f23cd8b066 ] The type of timespec64::tv_nsec is 'unsigned long', while we have only u32 for on-disk and in-memory. This wastes a few bytes in btrfs_inode. Add separate members for sec and nsec with the corresponding type width. This creates a 4 byte hole in btrfs_inode which can be utilized in the future.

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.
