In bch_mca_scan(), There are some confusion and logical error in the use of loop variables. In this patch, we clarify them as: 1) nr: the number of btree nodes needs to scan, which will decrease after we scan a btree node, and should not be less than 0; 2) i: the number of btree nodes have scanned, includes both btree_cache_freeable and btree_cache, which should not be bigger than btree_cache_used; 3) freed: the number of btree nodes have freed.

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.
