We used a per-descriptor SRCU struct in order to not impose a wait with synchronize_srcu() for descriptor X on read-only operations of descriptor Y. Now that we no longer call synchronize_srcu() on descriptor label change but only when releasing descriptor resources, we can use a single SRCU structure for all GPIO descriptors in a given chip.

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.
