Linux kernel source tree
e73e5b7c1a
The rcu_torture_one_read() function is designed for RCU readers that are confined to a task, such that a single thread of control extends from the beginning of a given RCU read-side critical section to its end. This does not suffice for things like srcu_down_read() and srcu_up_read(), where the critical section might start at task level and end in a timer handler. This commit therefore creates separate init_rcu_torture_one_read_state(), rcu_torture_one_read_start(), and rcu_torture_one_read_end() functions, along with a rcu_torture_one_read_state structure to coordinate their actions. These will be used to create tests for srcu_down_read() and friends. One caution: The caller to rcu_torture_one_read_start() must enter the initial read-side critical section prior to the call. This enables use of non-standard primitives such as srcu_down_read() while still using the same validation code. Signed-off-by: Paul E.

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.
