Now that it is legal to invoke srcu_read_lock() and srcu_read_unlock()
for a given srcu_struct from both process context and {soft,}irq
handlers, it is time to test it. This commit therefore enables
testing of SRCU readers from rcutorture's timer handler, using in_task()
to determine whether or not it is safe to sleep in the SRCU read-side
critical sections.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
