The old calculation assumed that the label space was 128k and the label size is 128. With v1.2 labels where the label size is 256 this calculation will return zero. We are saved by the fact that the nsindex_size is always pre-initialized from a previous 128 byte assumption and we are lucky that the index sizes turn out the same. Fix this going forward in case we start encountering different geometries of label areas besides 128k. Since the label size can change from one call to the next, drop the caching of nsindex_size.

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.
