At seqlock.h, the following set of functions:
- __seqcount_ptr()
- __seqcount_preemptible()
- __seqcount_assert()
act as plain seqcount_t "property" accessors. Meanwhile, the following
group:
- __seqcount_ptr()
- __seqcount_lock_preemptible()
- __seqcount_assert_lock_held()
act as the equivalent set, but in the generic form, taking either
seqcount_t or any of the seqcount_LOCKNAME_t variants.
This is quite confusing, especially the first member where it is called
exactly the same in both groups.
Differentiate the first group by using "__seqprop" as prefix, and also
use that same prefix for all of seqcount_LOCKNAME_t property accessors.
While at it, constify the property accessors first parameter when
appropriate.

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.
