Fix various sync state issues causing racy/bogus sync ratio, sync_action ad health chars in dm_status() info output. Sync ratio could be N/N (i.e. 100%) shortly after raid set creation, i.e. creating a new RaidLV or upconverting a linear LV to raid1 thus: "0 2097152 raid raid1 2 Aa 2097162/2097152 recover 0 0 -" instead of: "0 2097152 raid raid1 2 Aa 0/2097152 idle 0 0 -" Sync action could be non-idle, when the MD thread was done with io. Health chars could be 'A' when they should be 'a' for a short time before a resynchonization started.

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.
