![]() Three separate places in md.c check if the number of active writes is zero and, if so, sets mddev->in_sync. There are a few differences, but there shouldn't be: - it is always appropriate to notify the change in sysfs_state, and there is no need to do this outside a spin-locked region. - we never need to check ->recovery_cp. The state of resync is not relevant for whether there are any pending writes or not (which is what ->in_sync reports). So create set_in_sync() which does the correct tests and makes the correct changes, and call this in all three places. Any behaviour changes here a minor and cosmetic.

README
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.
