In current version, after scan_free_nid_bits, the scan is over if nid_cnt[FREE_NID] != 0. In most cases, there are still free nids in the free list during the scan, and scan_free_nid_bits usually can't increase nid_cnt[FREE_NID]. It causes that __build_free_nids is called many times without solving the shortage of the free nids. This patch fixes that.

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.
