The locking feature lists don't match reality as of v5.3-rc1: * arm64 moved to queued spinlocks in commit:c11090474d("arm64: locking: Replace ticket lock implementation with qspinlock") * xtensa moved to queued spinlocks and rwlocks in commit:579afe866f("xtensa: use generic spinlock/rwlock implementation") * architecture-specific rwsem support was removed in commit:46ad0840b1("locking/rwsem: Remove arch specific rwsem files") So update the feature lists accordingly, and remove the now redundant rwsem-optimized list.

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.
