asm-generic: New generic ticket-based spinlock This contains a new ticket-based spinlock that uses only generic atomics and doesn't require as much from the memory system as qspinlock does in order to be fair. It also includes a bit of documentation about the qspinlock and qrwlock fairness requirements. This will soon be used by a handful of architectures that don't meet the qspinlock requirements. * tag 'generic-ticket-spinlocks-v6': csky: Move to generic ticket-spinlock RISC-V: Move to queued RW locks RISC-V: Move to generic spinlocks openrisc: Move to ticket-spinlock asm-generic: qrwlock: Document the spinlock fairness requirements asm-generic: qspinlock: Indicate the use of mixed-size atomics asm-generic: ticket-lock: New generic ticket-based spinlock
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.
