mainlining shenanigans
6308f34775
The code in srcu_gp_end() inserts a delay every 0x3ff grace periods in order to prevent SRCU grace-period work from consuming an entire CPU when there is a long sequence of expedited SRCU grace-period requests. However, all of SRCU's grace-period work is carried out in workqueues, which are in turn within kthreads, which are automatically throttled as needed by the scheduler. In particular, if there is plenty of idle time, there is no point in throttling. This commit therefore removes the expedited SRCU grace-period throttling. Signed-off-by: Paul E.

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.
