Introduce a type representing a specific point in time. We could use the Ktime type but C's ktime_t is used for both timestamp and timedelta. To avoid confusion, introduce a new Instant type for timestamp. Rename Ktime to Instant and modify their methods for timestamp. Implement the subtraction operator for Instant: Delta = Instant A - Instant B Reviewed-by: Boqun Feng <boqun.feng@gmail.com> Reviewed-by: Gary Guo <gary@garyguo.net> Reviewed-by: Fiona Behrens <me@kloenk.dev> Tested-by: Daniel Almeida <daniel.almeida@collabora.com> Reviewed-by: Andreas Hindborg <a.hindborg@kernel.org> Signed-off-by: FUJITA Tomonori <fujita.tomonori@gmail.com> Link: https://lore.kernel.org/r/20250423192857.199712-5-fujita.tomonori@gmail.com Signed-off-by: Andreas Hindborg <a.hindborg@kernel.org>
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.
